Question

Use the formula for the probability of the complement of an event.

Two dice are tossed. What is the probability of not getting a sum of 8? (Enter your probability as a fraction.)

Answer 1

Pr(~8)= 1 - Pr(8)= 1- 5/36=(36-5)/36= 31/36

6x6= possible outcomes= 36

5 ways to get 8

44,53,35, 62, 26

31 ways to not get 8
