rx10 you forgot to count the inverse of your dice throws, i.e
(3,1), (4,1), etc

so the total number should be 20 out of 36, or 10/18 which is not one of the answers Carcass

the difference is always the same. You cannot double count.

The pair is one

If you throw off your dices and the result is both 6 on both faces you count two times ?
