In a game of bridge, the entire deck of 52 cards is dealt out to 4 players so each player's hand is made up of 13 cards. You are one of the players, so you can think of your hand as a sample of size 13 drawn from a population of 52. The total number of bridge hands is since the dealer is choosing a sample of 13 out of 52 cards when they deal your hand. This is the size of the sample space and will serve as the denominator in the probabilities below.
What is the probability that your hand has the Ace of Spades?
What is the probability that your hand has no Aces?
What is the probability that your hand has at least one Ace?
What is the probability that your hand has exactly one Ace?
What is the probability that your hand has exactly two Aces?
What is the probability that your hand has all four Aces?
