a) Complete the possibility space.

5

b) What is the probability of scoring a total of 6?

c) What is the probability of scoring a total greater than 10?

Answer 1

Explanation:

b) what is the probability of scoring a total of 6?

b) = 2/9

C) what is the probation scoring a total greater than 10

c)= 3/9

Answer 2

2/9 ; 4/9

Explanation:

______SPINNER A_____

_____ 2 ____ 4 _____ 6

1 ____ 2 _____4 _____6

3____ 6 _____12____ 18

5____10_____20____30

4 * 3 = 12 ; 5 * 2 = 10 ; 5 * 6 = 30

Probability of scoring a total of 6 :

From the sample space ; Number of 6's = 2

Total sample space = 9

Recall : probability = required outcome / Total possible outcomes

P(total of 6) = 2 / 9

P(total greater than 10) :

Required outcome ; > 10 = (12, 18, 20, 30) = 4

P(total > 10) = 4 / 9
