There are 6%5E2 or 36 possible outcomes
1,1 1,2 1,3 1,4 1,5 1,6
2,1 2,2 2,3 2,4 2,5 2,6
3,1 3,2 3,3 3,4 3,5 3,6
4,1 4,2 4,3 4,4 4,5 4,6
5,1 5,2 5,3 5,4 5,5 5,6
6,1 6,2 6,3 6,4 6,5 6,6
1) P=1%2F36
2) P=6%2F36=1%2F6

Here are all the sums using the same order as above
2 3 4 5 6 7
3 4 5 6 7 8
4 5 6 7 8 9
5 6 7 8 9 10
6 7 8 9 10 11
7 8 9 10 11 12
.

3)P=2%2F36=1%2F18
4)P=15%2F36=5%2F12
5)P=10%2F36=5%2F18
6)P=6%2F36=1%2F6

36 possible outcomes: P = Particular/ALL possible
P(2 6s) = 1/36
P(double) = 6/36 = 1/6
P(sum 11) = 2/36 = 1/18
etc: Count them...
