Study Notes
Mutually Exclusive Events
- Mutually exclusive events cannot occur at the same time.
- Probability formula: P(A or B) = P(A) + P(B).
General Addition Rule
- Applies to any two events, whether they are mutually exclusive or not.
- Probability formula: P(A or B) = P(A) + P(B) - P(A and B).
General Multiplication Rule
- Used to find the probability of the occurrence of two events A and B together.
- Probability formula: P(A and B) = P(A) * P(B|A), where P(B|A) is the conditional probability of B given A.
Multiplication Rule for Independent Events
- For independent events, the occurrence of one does not affect the other.
- Probability formula: P(A and B) = P(A) * P(B).
Conditional Probability Formula
- Conditional probability measures the likelihood of an event occurring given that another event has already occurred.
- Probability formula: P(B|A) = P(A and B) / P(A).
