At Papa John's you are deciding on what you want for dinner. The pizza offers 8 different meats, 4 different cheeses, 3 different crust types and 2 different sauces. How many different pizzas do you have to choose from? (Hint: Use a list, tree diagram, or Fundamental Counting Principle.)

• 32

• 192

• 40,320

• 51,200

How many outfits are possible with 2 pairs of jeans, 5 t-shirts, and 2 pairs of shoes? (Hint: Use a list, tree diagram or the Fundamental Counting Principle.)

• 9

• 40

• 20

• 10

What is the purpose of a tree diagram?

• To make the problem pretty.

• To show the total number of outcomes in a probability experiment.

• To find the area of the sample space in a probability experiment.

• To see if it is a experimental or a theoretical probability

What is a sample space?

• The answer to a probability problem.

• The area or perimeter of a probability.

• The total number of different results (or outcomes) you could get from an experiment.

• A probability that is always written as a percent.

You can make an outfit by picking 1 of 3 different shirts and match it with 1 of 2 different pants. What is size of the sample space?

• 6 Different Outfits (Black shirt, Black Pants) (Black Shirt, Jeans) (Brown Shirt, Black Pants) (Brown Shirt, Jeans) (White Shirt, Black Pants) (White Shirt, Jeans)

• 2 Different Outfits (Shirt, Black Pants) (Shirt, Jeans)

• 3 Different Outfits (Black Shirt, Pants) (Brown Shirt, Pants) (White Shirt, Pants)

• 1 Outfit (Shirt, Pants)

Use the tree chart to find the probability of randomly picking an outfit with a white shirt and jeans.

• There are 6 outfits

• 2/6, or 2 out of the 6 outfits have a white shirt with jeans

• 3/6, or 3 out of the 6 outfits have a white shirt with jeans

• 1/6, or 1 out of the 6 outfits has a white shirt with jeans.

For breakfast, you can choose to eat cereal or a bagel and to drink coffee, OJ, tea, or water. What is the sample space of this situation?

• 2, because there are 2 things to choose from to eat.

• 4, because there are 4 things to choose from to drink

• 10, because I see 10 different words on the tree diagram

• 8, because there are 8 different outcomes (cereal, coffee) (cereal, OJ) (cereal, tea) (cereal, water) (bagel, coffee) (bagel, OJ) (bagel, tea) (bagel, water)
