Complete the sample space diagram on your whiteboards Sample Space Diagrams This table is one way of displaying all the outcomes from throwing two dice and adding them together. It is called a sample space diagram 9 6 5 4 8 3 2 1 + Second die First die Complete the sample space diagram on your whiteboards

Sample Space Diagrams The sample space diagram can be used to find probabilities. What is the probability of getting a total more than 5? What is the probability of getting a total less than 10? What is the probability of getting a total that is a square number? What is the probability of getting an even total? What is the probability of getting an odd total? What is the probability of getting a total less than 13? 12 11 10 9 8 7 6 5 4 3 2 1 + Second die First die 2 3 4 5 6 7 3 4 5 6 7 8 4 5 6 7 8 9 5 6 7 8 9 10 6 7 8 9 10 11 7 8 9 10 11 12

if the difference is 1 or 2: Anton wins Two Dice Games: Use sample space diagrams to show how you decide whether the game is fair. (1) (2) two dice are rolled and the numbers on each dice are subtracted (smaller from larger) if the difference is 1 or 2: Anton wins if the difference is 0, 3, 4 or 5: Brisa wins is this a fair game? two dice are rolled and the numbers on each dice are added if the total is prime: Adrian wins if the total is composite (not prime): Bella wins is this a fair game? (3) (4) two dice are rolled and the numbers on each are multiplied and then this is divided by 5 the score is the remainder e.g. for (1, 3) you get 3  5 the remainder is 3 if the remainder is 0 or 1: Alice wins if the remainder is 2, 3 or 4: Bram wins is this a fair game? two dice are rolled and the numbers on each are multiplied and then this is divided by 3 the score is the remainder e.g. for (2, 5) you get 10  3 the remainder is 1 if the remainder is 0: Alwyn wins if the remainder is 1 or 2: Bart wins is this a fair game?

Complete the sample space diagram on your whiteboards Sample Space Diagrams Two four sided dice are thrown and the numbers added together. Complete the sample space diagram on your whiteboards What is the probability of getting: a total more than 4? a total less than 8? a prime number total? a total that is at least 3? a total of 4 or 5? the same number on both dice? a lower number on the first dice? 8 7 6 5 4 3 2 1 + Second die First die

Sample Space Diagrams 8 7 6 5 4 3 2 1 + 6 5 4 3 7 2 6 5 4 3 Second die First die Use the table to find the probability of getting a score of 3 or 4. 6 5 4 3 7 2 6 5 4 3 The probability of getting a score of 3 or 4 can be written as P(3 or 4). P(3 or 4) = 5 16 7 16 P(5 or 6) = 3 16 P(2 or 7) =
