Find some conditional probabilities
Beth knows the probabilities for her genetic types from part (c) of the previous exercise. She marries Bob, who is albino. Bob's genetic type must be aa.
(a) What is the conditional probability that a child of Beth and Bob is non-albino if Beth has type Aa? What is the conditional probability of a non-albino child if Beth has type AA?
(b) Beth and Bob's ?rst child is non-albino. What is the conditional probability that Beth is a carrier, typeAa?
