All possible outcomes: 2,3,4,5,6,7,8,9,10,11,12
All possible outcomes that are prime: 2,3,5,7,11
All possible rolls that are one of these prime numbers:
--1-2-3-4-5-6
1.*.*....*....*
2.*....*....*...
3....*....*......
4.*....*.........
5....*..........*
6.*..........*...
So we count 15 possible ways to make a Prime number.
P = (# of correct outcomes) / (# of total possible outcomes)
P = 15 / (6*6) = 0.416667 or 5/12
