Time left 0:47:0 Assume that you take a multiple-choice test with n options for each question. The probability that you know the answer is p in answering a question on this test. If you don't know the answer, you pick one randomly. Given that you answered a question correctly, what is the probability that you knew the answer to it? a. n/(pn+1-p) pn/(n+1-p) C. pn/(pn+1-p) d. pn/(pn+n-p) Cleat/ww.choice. Next page
