You can put this solution on YOUR website! prime numbers are 2,3,5,7, and 11
This has a probability of (1+2+4+6+2)/36=15/36
=====================
odd numbers are 3,5,7,9,11 and have a sum of (2+4+6+4+2)/36=1/2. This is the highest.
Same numbers are 1/36 each, and there are 6, so that is 6/36
Where one is a 5 includes 1-5 5-1;2-5, 5-2,...6-5, 5-6, or 12/36
