Formula and methodology
Formula: P(A|B) = P(A and B)/P(B).
The conditional probability restricts attention to outcomes in event B and measures the share that also belong to event A.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Joint probability P(A and B) — minimum 0; maximum 1
- Condition probability P(B) — minimum 1.0E-6; maximum 1
Worked example
| Input | Value |
|---|---|
| Joint probability P(A and B) | 0.2 |
| Condition probability P(B) | 0.5 |
P(A|B) = 0.4.
Assumptions and limits
- Both inputs are probabilities from 0 through 1.
- The joint probability cannot exceed the conditioning-event probability.
- No independence assumption is made.
