, including anything entered into your TI-84 or any Excel commands.
1.
A certain person has the following number of shirts, pants, and shoes in their (very
small) closet:
5 shirts
4 pants
2 shoes Use counting techniques to determine the number of unique outfits that can be made
with these clothes.
A standard deck of cards consists of 52 distinct cards. Each card has a “face value” of 2 through
10, Jack, Queen, King, and Ace (giving 13 possible face values), as well as a “suit” of either
Spades, Clubs, Hearts, or Diamonds.
2.
Use counting techniques to calculate the number of different arrangements of the 52
cards. (This number is very large, so you can just write down how you calculated it)
3.
In (a simplified version of) the card game Five-Card Poker, you are dealt a “hand”
consisting of five cards from the top of the deck, and the order of your five cards does
not matter. Use counting techniques to determine how many different hands are
possible in Five-Card Poker.
4.
In Five-Card Poker, a royal flush is the rarest possible hand, consisting of the Ace, King,
Queen, Jack, and 10, all of the same suit. What is the probability that you are dealt a
royal flush? You can leave your answer as an unreduced fraction.
5.
In (a simplified version of) the card game Blackjack, you are dealt a “starting hand”
consisting of two cards from the top of the deck, and the order of your two cards does

6. In Blackjack, a blackjack occurs when your starting hand consists of an Ace and either a
10, Jack, Queen, or King, all of any suit. What is the probability that you are dealt a
blackjack? You can leave your answer as an unreduced fraction.
In a certain experiment, we are interested in two different events occurring, and their

3
.52
B
c

7.
Calculate P(A)
. Round to 4 decimal places if necessary.
8.
Calculate P(A ∪ B)
. Round to 4 decimal places if necessary.
9.
Calculate P(A|B)
. Round to 4 decimal places if necessary.
10.
Are A
and B
independent? Why or why not?
11.
