Question

James is playing a dice game. He is rolling two 6-sided dice. To win, the two dice must sum to a

number greater than 7. What is the probability that he will win?

Answer 1

9/20

Explanation:

4+4=8, 4+5=9, 4+6=10, 5+5=10, 5+6=11, and 6+6=12 are the nine possible roll combinations that have a sum greater than 7 out of the possible 20 different combinations. This makes the probability of rolling a sum greater than 7 a nine in twenty chance.
