Suppose that the probability of a person having fair hair is 0.2, that the probability of a person having fair hair given that the person has freckles is 0.4, and that the probability of a person having freckles is 0.06. Find the probability that a person has freckles given that the person has fair hair. Last edited by sita; March 4th, 2018 at 09:39 AM.
