Question: 1. A psychologist states that there is a 5% chance (p = .05) that his decision will be wrong. Assuming complementary outcomes, what is the probability that his decision will be correct?

2. The probability that a student passes a class is p(P) =.59. The probability that a student studied for a class is p(S) = .53. The probability that a student passes a class given that he or she studied for the class is p(P/S) = .89. What is the probability that a student studied for the class, given that he or she passed the class [p(S/P)]?
