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)
