Kelsey is asked to find the probability of rolling a composite number on a die. She states that this is a simple event. True or false?

I think it's true cause

Here are the probabilities for getting a sums 2-12. (you can't get 1 as a sum after rolling two die)

2 - 1/36

3 - 2/36 = 1/18

4 - 3/36 = 1/12

5 - 4/36 = 1/9

6 - 5/36

7 - 6/36 = 1/6

8 - 5/36

9 - 4/36 = 1/9

10 - 3/36 = 1/12

11 - 2/36 = 1/18

12 - 1/36

Since composite numbers are 4,6,8,9,10,12. Add up the probabilities for all of those.

21/36=7/12
