Question

Donna and Kaia are playing a game involving two fair number cubes with faces labeled 1 through 6. If Donna tosses a sum of 8 on her next turn, she wins the game. Otherwise the game continues.

What is the probability that Donna will win on her next turn?

Answer 1

To get a sum of eight the first die must be 2 or greater and the second die must be one specific value that makes the sum equal to 8 with respect to the first die.

So the probability of Donna winning on her next turn, rolling a sum of 8 is:

(5/6)(1/6)=5/36
