Question

I roll two fair six-sided dice. What is the probability that my roll totals 8?

8/36
6/36
5/36
3/36

Answer 1

Probability is total desired outcomes over total possible outcomes.

6 outcomes on die #1: 1, 2, 3, 4, 5, 6
6 outcomes on die #2: 1, 2, 3, 4, 5, 6

6 x 6 = 36 possible outcomes.

How many ways to make 8? 2,6; 6,2; 3,5; 5,3; 4,4; 4,4
Remember, each pair is different since there are two dice.

Therefore, 8/36 probability of rolling an 8.
