An urn contains 140 slips numbered 1, 2, . . , 140 (a) (20 points) first assume that a set of 5 slips is chosen (5 choices without replacement). compute the probability that for the 5 slips, the maximum of the numbers on them is at most 70. (b) (20 points) assume instead that 5 slips are chosen with replacement after each choice. compute the probability that for the 5 slips, the maximum of the numbers on them is at most 70
