A “random digit" is a number chosen at random from {0,1, ... ,9}, each with equal probability. A statistician choses n random digits. (a) For k What is the probability of A, as a function of k and n? 0, 1, ... , 9, let A be the event that all the digits are k or smaller. (b) Let B be the event that the largest digit chosen is equal to k. What is the probability of B? Justify your answer carefully.
