History of Probability (MAT 142) Objectives Determine what fraction of a deck of cards a certain set of cards describes. Determine how many of a certain type of card is in a deck. Determine the number of times two head, two tails, and one head and one tail will come up when two coins are tossed.

Standard Deck of Cards

How many spades are in a standard deck of cards? What fraction of a deck is spades?

How many queens are in a standard deck of card? History of Probability (MAT 142) How many queens are in a standard deck of card? What fraction of a deck is queens?

History of Probability (MAT 142) If you flip a pair of coins 20 times, approximately how many times do you think a pair of tails will come up? Flip a pair of coins 20 times. Did a pair of tails come up as many times as you approximated?
