Question
Part I: Probability
For each of the following problems, you should write your answer as an expression. Do not
give the final numeric value. For example, you should write C(4,2)/24 instead of 0.375.
3.
A standard deck of playing cards consists of 52 cards. Each card has a
rank and a suit. There are 13 possible ranks (A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K), 4 possible
suits (spades, clubs, hearts, diamonds), and 13 cards in each suit (one of each rank).
A hand of 9 cards is drawn from a standard deck of 52 cards (assume all outcomes are
equally likely).
3.1 What is the probability that a hand of 9 cards is all the same suit (for example, all
hearts)?
3.2 What is the probability that a hand of 9 cards has four cards of one suit and five cards
of another suit (for example, four hearts and five diamonds)?
3.3 What is the probability that a hand of 9 cards has three cards of one rank, three cards
of a second rank, and three cards of a third rank (for example, three A's, three 4's, and
three K's)?
