The student misplaced his notebook; however, he remembers that the notebook is in one of the "n' lockers. The probability that the notebook is in the jth locker is a¡, j=1,2,3,..., n. If he searches the jth locker and that the notebook is there, the probability that he will find it is given by Bj. Find the probability that the notebook is in the jth locker, given that the student has already checked the jth locker but has failed to find it. Hint: A proper event composition may be needed in answering the problem
