1. The problem statement, all variables and given/known data Eight cards are selected with replacement from a standard pack of 52 playing cards, with 12 picture cards, 20 odd cards, and 20 even cards. (a) How many different sequences of eight cards are possible? (b) How many of the sequences in part (a) will contain three picture cards, three odd cards and two even cards? 2. The attempt at a solution The first part is fairly straightforward. Given 8 available slots with 52 different choices for each slot, one can conclude that the number of different sequences of cards is 528. I am, however, stumped by the second part.
