Question

Conditional Probability

Ice cream 70% of your friends like chocolate, and 35% like chocolate AND like strawberry. What percent of those who like Chocolate also like strawberry?

Answer 1

The percent of those who like chocolate and also like strawberry is 50%.

Step-by-step explanation:

To find the percent of those who like chocolate also like strawberry, we need to use conditional probability. The formula for conditional probability is:

P(A|B) = P(A ∩ B) / P(B)

In this case, A represents liking chocolate AND strawberry, and B represents liking chocolate. We are given that P(A) = 0.35 and P(B) = 0.70. Plugging these values into the formula, we get:

P(A|B) = 0.35 / 0.70 = 0.5

Therefore, 50% of those who like chocolate also like strawberry.
