Bayes’ Theorem is an important probability result relating the condition probabilities P(A|B) and P(B|A). Here we develop the formula. (a) Let A and B be events. What is the definition of P(A|B)? What is the definition of (B|A)? (b) Compute P(A|B)·P(B) and P(B|A)·P(A). (c) Find an expression for P(B|A) in terms of P(A), P(B) and P(A|B). (d) Suppose P(B) =P(A) and P(A|B) = 0.7, find P(B|A).

Problem 4 ((30 points) Bayes Theorem). The local barber shop is home to three barbers The barbers appear identical but vary in their ability to provide good haircuts. Denote the event that you receive a good haircut by G, the event that you do not receive a good haircut by NG, and the event that your hair is cut by barber i by Bi, where i E 1,2, 3) The probability that any particular barber cuts your hair is 1/3....
