Probability Formulas
| Type | Formula | Description |
|---|---|---|
| Single Event | P(A) = favorable/total | Probability of a single event occurring |
| Independent Events | P(A and B) = P(A) × P(B) | Probability of two independent events occurring together |
| Dependent Events | P(A and B) = P(A) × P(B|A) | Probability of two dependent events occurring together |
| Conditional Probability | P(A|B) = P(A∩B)/P(B) | Probability of event A occurring given that B has occurred |
Where:
- P(A) = Probability of event A
- P(B) = Probability of event B
- P(A|B) = Probability of A given B
- P(A∩B) = Probability of A and B occurring together
