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.
draw an 8 by 12 grid whihc represents all the possibly outcomes, (96 in total)
tick of all the favourable boxes and count them. how many are there
