Best ResponseYou've already chosen the best response.1It would be helpful if we knew all the possible sums of the dice. I think it is easiest to use a table with numbers 16 on the top row and 16 on the left column, and just compute all the sums. Then we can easily see all the prime sums from the table. dw:1349635556005:dw

Best ResponseYou've already chosen the best response.0I tried that and I missed a few sums. Your table makes it more clear. Thank you. very much. So it would be 15/36 reduced into 5/12 correct?
