How this calculator works
Odds=p/(1−p); probability=odds/(1+odds).
Formula
odds=p/(1−p); p=odds/(1+odds)Converts between probability and odds.
Worked example
Three to one odds is a verified test case used by the calculation engine.
Assumptions and limitations
- Provide exactly one input representation.
- Probability is between 0 and 1.
- Odds are non-negative.
