Two dice are rolled. Find the odds that the score on the dice is either 7 or 12

Answer 1

Imagine that the dice are numbered A and B. There are 36 possible results. Six of the combinations add up to 7
A---B
1 & 6
2 & 5
3 % 4
4 & 3
5 & 2
6 & 1
and only one combination (6 & 6) adds up to 12.

What does that tell you?
