Suppose that students in a statistics course were asked whether they preferred multiple choice questions or whether they preferred short answer questions. You are given that x% said that they preferred multiple choice questions. y% of the students were male. z% of the males preferred multiple choice. You want to calculate the probability that a student is male, given that the randomly selected student prefers short answer questions. Which of the following formulas is correct? P(M): probability that a student is male P(MC): probability that a student prefers multiple choice
