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

127 millimeters is the answer
