Question

A student has access to professor evaluations. Overall, he has enjoyed 70% of all classes he has taken. He finds that of the courses he has enjoyed, 13% were taught by professors with poor evaluations. 84% of the courses he has taken were taught by professors with good evaluations. What is the probability that the class was taught by a professor with a poor evaluation and that the student enjoyed the class? What is the probability that the student enjoyed the class given that it was taught by a professor with a good evaluation? Suppose the student signed up for three courses next semester, all of which are taught by professors with good evaluation. What is the probability he enjoys all three?
