Formula and methodology
Formula: P(A|B) = P(B|A) × P(A) / P(B).
Scales the likelihood by the rare base rate, then normalizes by overall evidence. Rare conditions stay unlikely even with strong signals.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- P(B|A) — minimum 0; maximum 1
- P(A) — Base rate, above 0.; minimum 0; maximum 1
- P(B) — Evidence rate, above 0.; minimum 0; maximum 1
Worked example
| Input | Value |
|---|---|
| P(B|A) | 0.9 |
| P(A) | 0.01 |
| P(B) | 0.05 |
P(A|B) = 0.18.
Assumptions and limits
- P(A) and P(B) are positive and at most 1.
- Inputs are coherent probabilities for the same population.
