P: 1

Hi to all!
I don`t know to do this tasks, so I would much apriciate if someone can help 1) The student fills IQ test (true  false based).There is m offered answers on each of N questions. For every question student knows the answer (with probability P) or answering by random (with probability 1P), and his answer is correct with the probability of 1/m. a) Determine the probability that the student really knew the answer to the first question, if we know that he gave a correct answer. b) Determine the probability that the student will complete correctly the entire test. 2) Two points are randomly selected (M1 and M2) along the line L (L => 1). Determine the probability that the M1M2 <1? Desperately need help :(
