Question

A survey of the men in a certain town showed that 35% of the men have blond hair and 14% of them have blond hair and blue eyes. What is the probability that a randomly selected man has blue eyes, given that he has blond hair?

Answer 1

If you are given he has blond hair, so the total probability will be 35%. And among them, he needs to have blue eyes, its probability is 14% among the 35%. So the final probability is 14%/35%=40%.
