Working Mathematically Stages 5. Reading Maths: Practical applications of probability sir. I want to choose the 9. This will be a number from 0 to 1. The probability of choosing the 9 is: The theoretical probability of an event.
What is the probability of choosing the 9?
Solution The cards are: Group A is made up entirely of boys. E I will travel overseas next month.
A student is chosen at random from each group. B We will have rain tomorrow. Luke had 13 clear and 7 pearl light globes. He selected one of these at random. H My favourite netball team will win at least one of its next three matches. G I will sit for a mathematics test during the next three months. F I will live to the age of What would be the probability that the globe was: D I can walk from home to the Sydney Harbour Bridge without resting.
C There will be a holiday on 25 December. Give reasons for your answer. What is the probability that it was: B and C. If I choose one tree at random. Make a list of all 0. If one ticket is drawn at random from the barrel. Heather saw the light on her way home from work. Orange 2 14 c is a male who chooses orange? Fawn 7 3 d is a female who chooses green?
Other 2 3 e is not a female who chooses green? Totals g chooses neither green nor gold? Gold 44 32 If one of these people is chosen at random. The results are shown in the table on the right.
The information below was collected. This is used as an estimate of the theoretical probability. What is the probability that I will not die this year? Use these results to estimate the probability that a CD produced by this factory would be: Their statistics are given below: What is the probability that the sum is neither 5 nor 6?
What is the chance that I will not be sent? What is the probability of getting fewer than 3 heads? Does this represent good value? Explain your answer. The results are written below. The results are shown 18 Frequency on this graph. Use these to complete the table on the right. Complete the table. Use these results to 15 find the experimental probability of 12 throwing a total: In each case. Result Tally Freq. Test your spinner over 50 trials.
Repeat the process at least 20 times and average the results. Is the game fair? Who is expected to win in the long run? Write the answers ii 1?
What did you find? Investigate this question by recording the number of throws needed. What is the probability that it is: O a vowel?
M a consonant? E a club?
O not an Ace? C a 5 or a diamond? H a diamond or a spade? What is the probability that the counter is: A yellow? H not yellow? C green? D not green? O white? E either white or yellow? S red? T either red or yellow? O a spade? M not a spade? S a court card? E black? S not an Ace? O not a court card? T a number between 2 and 8? Sometimes other types of diagrams are used. List all ordered pairs of counting numbers. What is the sample space?
Solution To show the outcomes. The sample space for throwing one dice. Show all possible outcomes. We need to use efficient ways of organising the complete sample space of compound events.
The set of all possible outcomes of an event is called the sample space of that event. We could use a list. Show all possible outcomes to this compound event as: E 2 Show the possible outcomes 3 for question 1 as a tree 10 9 5 5 diagram. How many outcomes would be in the sample space of this compound event? Show the sample space of this compound event as: Find the probability of choosing two Aces from a standard pack of cards in two draws: The tree diagram below shows the sample space of this experiment.
Exercise 1 Trial the game.
Dependent events are events where the outcome of one event will affect the possible outcomes of the other. One card is drawn out and placed on a table. The highest total goes first. This is to be the tens digit of a two-digit number. The wording of a question will help you decide whether you are dealing with dependent or independent events. Another card is then drawn out of the hat and placed beside the first card to complete the number.
GOAL 4 Make up a game of your own that is unfair. Event 2: I choose a piece of fruit once again. Event 1: I choose a piece of fruit and eat it. If 6 is selected first. I take a card and then return it to the pack.
I take a card once again. The two events are dependent. I take a card and put it in my pocket. Do Questions 8.
I choose a piece of fruit and then return it to the bowl. In one of the boxes there is a diamond ring. Another card is then drawn out and placed beside the first card to complete the number. Would it improve her chances to win if she did so?
Explain why or why not. What is now the probability that the ring is in box A? It does not contain the ring. I had bought 3 tickets. The last ticket drawn out won the prize. She chooses box A. Had my chance of winning improved?
What was the probability of my winning then? The other two are empty. The tickets were taken out one at a time. A 3 James Luke A 1. J 3 James Alan L 1. The names being considered are Alana. One person cannot fill both positions. J 3 a How many possible ways are there of matching the name tags with the photos? The possible ways of matching the name tags to the photos are shown by this tree diagram. Alan and Luke had been separated from the photographs of these three people.
A 3 Luke Alan James L 1. E and F. L 3 James Luke Alan J 1. Naomi and Heather. I did not know what to believe. What is the probability of drawing them out in the same colour order shown here?
I wondered whether there might be a tendency in some families to have more children of one sex than the other. When my fourth child was a boy. Solution The total number of possible outcomes for three coins is 8.
We can mark a set of outcomes clearly on a dot diagram. For example. The dot diagram over the page shows the possible outcomes when two dice are tossed. T The tree diagram lays out. H b What is the probability of getting: H i 2 heads?
T ii a head and a tail in any order? Dot diagram showing all possible outcomes. On the diagram. July ? All possible outcomes are shown on this dot 6 diagram. Explain why this answer is obtained.
Copy this diagram and child child extend it for 3 children. Blue dice 4 c a sum of 2?
Australian Signpost Mathematics NSW > Sample Pages
Red dice o at least one dice even? Find the probability of getting: Tail 1 2 3 4 5 6 a a head and a three b a tail and a six c a tail on the coin d an even number on the dice e a tail on an even number f a tail on a number less than 4. Find the probability of: This is repeated 3 times.
Use the tree diagram to find the probability of tossing: Draw a dot diagram that shows the possible outcomes. The tree diagram on page 65 shows the sample space. Spin 2 3 b What is the probability of spinning: A card is drawn and placed on a table.
C and D are written on cards and placed in a hat. A ii DAD? B ii drawing the letters in alphabetical order? C D 10 A letter A. B or C is drawn from a hat and a random number that is either odd or even is obtained from a A random number calculator. In how many ways can this be done? What is the probability that: A second card is then drawn and placed to the right of the first card. A third card is then drawn and placed on the right of the other two. This is an application of subjective probability.
This means that the ordinary gambler is sure to lose over time. We can use the information in contingency tables to calculate probabilities. This is how the bookmaker. This is rarely the case. Orange 4 8 10 3 25 a the preference would be red? Totals 30 32 26 12 b the preference would not be red? Contingency table d it would be from a male? What colour should Blue?
This makes it easier to work out probabilities. Blue 9 11 6 6 32 If one of their preferences was chosen at random. The contingency table Red 11 10 8 2 31 summarises their preferences.
There were preferences altogether. If one is chosen at random. What is the probability that the person has: Yes a How many males were surveyed? No 62 b How many people answered no? What is the Music 16 21 37 probability that the student: Woodwork 13 10 23 b chose art? Totals 53 47 c did not choose woodwork?
Give your answers as decimals. What is the probability that the person: Art 26 16 40 One student is chosen at random. The record of their choices is shown in this table. Mathematics 50 10 a Use this information to complete Totals 90 60 the table. Age Number The age distribution of these people is shown in the table.
A member of the 42 belonged to both combined club was chosen at random. There were 86 people Tennis Golf in the tennis club and people in club club the golf club but only people in the combined club. What is the probability that the person chosen had belonged to: Half of the Library 30 females indicated psychology and Psychology 30 50 males and 10 females indicated mathematics. What is the theoretical Short 50 probability that the athlete is: Totals i short? The table shows the number of goals scored by each Craig 1 player in the team.
If a goal is played from Rajiv 7 the videotape at random. What is the probability that the employee has special skills in: Of these. Evan 0 a Craig? Mark 0 b Evan? Akos 6 c either Luke or Julian?
Nandor 5 d neither Akos nor Nandor? Luke 10 e someone who had scored 1 goal only? Julian 9 39 8 An engineering firm employs 87 people. An employee is chosen at random. Of those. John studied a number of accidents chosen at random from those that occurred during the years and How could the game be made fair? The details of fatal accidents occurring in Australia during that time are shown below. I always throw the dice first. A player must land on the home square to win. Explain why the change in probability is so small.
Simple equipment such as coins. She chose instead to use the random number key on her calculator. Solution 1 Step 1 Design an experiment Julia could have used a coin because there were only two equally likely possibilities: It allows you to consider likely outcomes in advance and to plan modifications before carrying out the real thing. Simulation is useful: If we choose a club or spade. This would lead to a conclusion 1 that the probability of Julia winning three games in a row is -.
Julia only won all three games once. Solution 2 Step 1 Design an experiment We could use a coin. Since Julia would expect this to occur as often as winning three games. Example 2 In 50 births at a local hospital. Julia lost all three games three times. It is. In that case. If it did. If 4 boys occur in a row. An inference is a judgement made using the information at hand. This last statement we have made is called an inference. Use each face of a dice to represent one of the shirts.
He used three coins with heads and tails representing boys and girls to simulate the birth of three children. Emily and Karim are all just as likely to win. He used 1 for January. Every Saturday night he chooses one of these shirts at random to wear to the dance. Design a simulation.
They intend to play a series of forty games. He wondered what the chances were of three children in the same family all being boys. He decided to use the Using inappropriate models sum of two dice to indicate the month in which each wedding can give absurd results. She has been made second reserve. By repeating this 11 times. Select one of these cards at random to determine if player number 1 is unfit. As there was always a surplus of people wishing to book the 20 sites.
Did Grace get to play in that game? To ensure randomness. Repeat the simulation 9 times to estimate the number of games Grace is likely to play. This meant that the site would be left vacant for the holidays. Use playing cards marked 1 to There are 20 wildlife cards in the set and they are placed inside the packets in a random fashion.
Draw cards at random and complete the table below. In how many of the trials were people turned away? Generating random integers A random number generator on a calculator or computer can be used to generate a set of integers by following these steps. Continue your simulation until you have two complete sets of cards. Do this at least 20 times. Find the range and mean of the class results.
If these numbers represented the faces on a dice. The player is out! The player with the highest total is the winner. What is the average number of balls faced before the person batting is out? If you want to record a one-digit random number.
When a zero occurs. Steps 1 Generate sets of two random numbers No. Use a tally. If your calculator gives only one random digit. Experiment 2 If two one-digit numbers are selected at random.
Just consider the last two digits given. Different colours Design a similar experiment of your own to find the could be used. This will also appear in the 2 2 formula bar at the top. One card is drawn out and 3: Section 1 a What is the probability of choosing a 9 from a list of random digits. What is the probability that the card will be: One of these cards is to be selected at random. What is the experimental probability that my score will be: Explain why the experimental probability that my score is higher than is not the real probability.
Show all possible outcomes: The dots show the ones we have in Standard 1 2 3 4 5 6 stock. The contingency table Blue 4 12 9 10 35 summarises their Green 8 2 7 2 19 preferences. If one of their preferences Totals 32 31 23 24 were chosen at random. If one is selected at x f random. Assume that each size is just Size as likely to be ordered. For the first page she must choose either red. Use 2 lemons.
If a piece of fruit is picked at this to determine the probability of the random. If Erica picks a card. Draw a tree diagram. D and E. The table shows the results for picking a a blond? Interest credited twice yearly. If the 3B 6 can catch with both their left hands and entire outside is painted. Minimum withdrawal is b If a and b are positive integers.

When saving or investing money: Now we will consider aspects of saving and borrowing. Disadvantages Lower interest rates are If you withdraw your money It usually requires the offered for savings accounts. The fixed amount receive a lower rate instead. Her first five cash or personal cheque withdrawals each month are free of bank transaction fees. Give your answer correct to three decimal places. Refer to the previous page if necessary. If a withdrawal is made.
What are these transaction fees? F8 1 What is referred to in cell: Make a spreadsheet of your own on a subject of your choice.
The same interest is paid for each time period. Find the simple interest charged for a loan of: Frame outside — more room! Sizes quoted are approximate.
Sewn-in floor and screened windows with storm flaps. But how much Trailmaster is 3 x 2. Read the Add-on living to suit your needs! Use these to determine the floor area inside the tent.
Your reasoning could be like this. Which is the best estimate of the interest charges for six months: Exercise 4: How much interest did she pay? At the end of the 5 years. What was the rate of simple interest charged? Which is the best estimate of the interest earned: Which is the best estimate of the interest charged: How much interest did she earn? Which is the best estimate of the interest charged for 6 years: How many women would you expect to join the club in 4 years?
How much did she give? Do not use a calculator for question 3. How much more interest does Jenny receive than Robert? How much interest did he pay? How much soil was lost? This was his contribution to family expenses. How much will Mona receive after 3 years? Julia heard that a famine was causing great suffering to many people in Africa. The interest in any time period is calculated using the original principal and so is the same for each time period.
This principle is included as part of the syllabus. Corresponding terms in columns can be added, subtracted, multiplied or divided by each other or by other numbers. This is a great way to start a lesson. The Language of Mathematics Within the coursebook, Mathematics literacy is addressed in three specific ways: id ID Cards see pp xvii—xxii review the language of Mathematics by asking students to identify common terms, shapes and symbols. They should be used as often as possible, either at the beginning of a lesson or as part of a test or examination.
These terms are also s te s tested in a Drag and Drop interactive that follows this section. They present Mathematics in the context of everyday reading An Answers section provides answers to all the exercises in the coursebook, including the ID Cards. Interactive Student CD This is provided at the back of the coursebook and is an important part of the total learning package. These are self-correcting and include multiple-choice, pattern-matching and fill-in-the-gaps style questions.
Results can be emailed directly to the teacher or parents. Drag and Drop interactives to improve mastery of basic skills. Animations to develop key skills by manipulating visually stimulating and interactive demonstrations of key mathematical concepts.
The places where these are treated are shown on the right. Where part of an outcome has been treated in Year 9, this is also indicated. The outcomes for Chapters 11 to 14 are optional topics as further preparation for the Mathematics Extension courses in Stage 6. These are indicated by the symbol. The syllabus strand Working Mathematically involves questioning, applying strategies, communicating, reasoning and reflecting.What does this mean? Assignments are provided at the end of each chapter.
The multiplication of two vectors vector arranges aksiomatichnyiy mathematical analysis, demonstrating all the nonsense of the foregoing. As there are only 5 flute players the other two sections of that circle will be zero and the remaining section of the violin circle will have 3 members to make the total of violin players 6.
