| Question | Answer |
| State the Addition Rule | P(A ∪ B) = P(A) + P(B) - P(A ∩ B) |
| State the Multiplication Rule used to find conditional probability | P(B|A) = (P(A ∩ B)) / P(B) | | V P(A ∩ B) = P(B|A) x P(B) |
| What does it mean when events are mutually exclusive? | The two events do not take place at the same time; they have no outcomes in common. |
| How is the Addition Rule applied to mutually exclusive events? | P(A ∪ B) = P(A) + P(B) because P(A ∩ B) is zero. |
