63.33% probability a randomly selected customer prefers Vanilla yogurt or is at least 25 years old

Step-by-step explanation:

A probability the number of desired outcomes divided by the number of total outcomes.

We are given the following chart:

                  Under 25 | At least 25

Chocolate: 40            |  15

Vanila:        20            | 40

Swirl:          15             | 20

What is the probability a randomly selected customer prefers Vanilla yogurt or is at least 25 years old?

There are 150 customers, which is the number of total outcomes.

Of those, 75 are at least 25 and 20 are under 25 and prefer Vanilla yogurt. So the number of desired outcomes is 75 + 20 = 95

95/150 = 0.6333
