1. Review of Probability

2. Probability of Simple Events
There is a bag that contains 6 white, 7 blue, 11 red, and 1 black marble. A marble is picked at random. Write each probability as a fraction, decimal, and a percent.
1. P(white) P(not blue)
3. P(red or black) P(yellow)

3. Counting Outcomes – Tree Diagrams
A penny is tossed and a 4 sided number cube with sides of 1, 2, 3 and 4 is rolled. Draw a tree diagram to show the possible outcomes. What is the probability of getting heads and an odd number? 1 2 H 3 4 1 2 T 3 4

4. Counting Outcomes – Fundamental Counting Principle
A car manufacturer makes 8 different models in 12 different colors. They also offer standard or automatic transmission. How many choices does a customer have?
Models(Colors)(Transmissions)=Total Number of Cars
8(12)(2) = 192
The customer can choose from 192 cars.

5. Probability of Compound Events
A card is picked from a standard deck of 52 cards and is not replaced. A second card is picked. What is the probability that both cards are red? Write your answer as a fraction, decimal and percent.
