Stanley’s statistics seminar is graded on a Pass/Fail basis. At the end of the semester each student is given the option of taking either a two-question exam (Final A) or a three-question exam (Final B). To pass the course, students must answer at least one question correctly on whichever exam they choose. The professor estimates that a typical student has a 45% chance of correctly answering each of the two questions on Final A and a 30% chance of correctly answering each of the three questions on Final B. Which exam should Stanley choose? Answer the question two different ways.
