# Multiplication Rule

### Independent Events

**p(A B) = p(A) · p(B) **

#### Example

A deck has 40 cards, one card is drawn and placed back in the deck and the second is then drawn. What is the probability of getting two aces?

### Dependent Events

**p(A B) = p(A) · p(B|A)**

#### Example

A deck has 40 cards, two cards are drawn simultaneously. What is the probability of getting two aces?
