Problem 3 A bag includes 8 balls, 3 of them are red and 5 of them are blue. (a) Select balls one by one from the bag without replacement until a red ball is selected or the bag is empty. Let Y be the number of selections. Find the PMF, CDF of Y, expected value of Y (E[Y]). (b) Select balls one by one from the bag with replacement until a red ball is selected. Let Y be the number of selections. Find the PMF, CDF of Y, expected value of Y (E[Y]).
