Given a multiple choice question with m = 10 choices, a student
either knows the answer or guesses. If she guesses, she chooses one
uniformly among the m choices. Let p = 0.8 be the probability that
the student knows the answer. Given that she answers the question
correctly, what is the conditional probability that she knew the
answer (rather than guessed)?
