A student is taking multiple choice exam in which each question has four possible answers, exactly one which is correct. If the student knows the answer he (she) selects one answer at random from the four possible answers. Suppose that the student knows the answers to 55% of the questions. If the student gets the correct answer to a question what is the probability that he or she knows the answer?
