Question

A child randomly selects a jellybean from a jar of jellybeans. The probability that the child selects a grape jellybean is 7/22, and the probability that he selects a grape jellybean or a cherry jellybean is 13/23. What is the probability that the child selects a cherry jellybean?

Answer 1

6/23

Explanation:

Since there are 7 grapes and 13 grapes AND cherry. 13-7 is 6. So the cherry jellybeans will be 6.
