Larry rolls a fair 8-sided die with faces labelled 1 through 8, and Yolanda rolls a fair 12-sided die with faces labelled 1 through 12. Suppose the probability that Larry rolls a smaller number than Yolanda is p/q, where p and q are relatively prime positive  numbers. Find p + q.

Harder than what?

Yes it is accurate and a little slow but it is not hard.
