The Rhetoric Department offers the popular course "Statistically Speaking" two times ayear. Students seem to like the course, both because it teaches them to integrate quantita-tive analyses into their argumentation, and because it is an easy A. The final (and only)exam in the course is a fifty-question multiple-choice test. If rhetoric major Rhett Butler knew the answer to forty of the questions, and selected an answer at random (from among five possible answers) for the remaining ten questions, what is the probability thathe actually knew the answer to a particular question that he got right?
