You can put this solution on YOUR website! There are 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
Look at the sums,
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
Then count the occurences of each sum,
2,1
3,2
4,3
5,4
6,5
7,6
8,5
9,4
10,3
11,2
12,1
Then divide by the total number of outcomes to get the probabilities,
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

-------------
sum = 2:: 1/36
sum = 3:: 2/36
sum = 4:: 3/36
sum = 5:: 4/36
sum = 6:: 5/36
sum = 7:: 6/36
sum = 8:: 5/36
sum = 9:: 4/36
sum = 10:: 3/36
sum = 11:: 2/36
sum = 12:: 1/36
