Problem 3. A standard deck of cards contains 52 cards:
13 Ranks: A,2,3,4,5,6,7,8,9,10,J,Q,K
4 Suits: Clubs, Diamonds, Hearts, Spades
Suppose you draw a hand of 5 cards from the deck. Consider the following possible hands of cards. For each part, explain how you derive your solutions.
3(a) How many different hands of 5 cards exist?
3(b) How many ways can you draw a single pair? A single pair means that there are exactly two cards with the same rank (no additional pairs and no 3 of a kind, etc.).
3(c) How many ways can you draw 4 of a kind? (4 cards of the same rank)
3(d) How many ways can you draw a full house? A full house is a pair of one rank and three cards of another rank.
3(e) How many ways can you draw a straight? A straight is 5
consecutive ranks. The Ace (A) can either go before 2 or after
K.
E.g., A,2,3,4,5 and 10,J,Q,K,A are both valid, as are 4,5,6,7,8 and
7,8,9,10,J etc.
Note: if you were to divide the number of hands of a particular type by the total number of 5 card hands, you would achieve the probability (odds) of randomly drawing a hand of that type.
