1. 12-7 Probability of Compound Events (AND problems) Goal: Find the probability of a compound event. Eligible Content: A1.2.3.3.1

2.  Independent Events – the outcome of one event does not affect the outcome of another event.  Probability of picking a red marble and a green marble from a bag.  Dependent Events – the outcome of one event affects the outcome of another event.  Probability of picking a student who is a girl and wears glasses. Vocabulary

3.  Multiply the probabilities together.  P(A and B) = P(A) * P(B)  Leave answers as fractions!!! Independent Events

4.  Multiply the probabilities together, but be careful when finding second probability.  P(A and B) = P(A) * P(B)  Leave answers as fractions!!! Dependent Events
