What This Calculator Does
Calculate probability and odds from favorable and total outcomes.
It combines Favorable Outcomes, Total Outcomes to estimate Probability, Odds For, Odds Against.
Formula & Method
Probability is P=\frac{Favorable}{Total} and percent P\%=100P. Odds for are \frac{Favorable}{Unfavorable} and odds against are \frac{Unfavorable}{Favorable}.
Notation used in the formulas: R = Probability; x_{1} = Favorable Outcomes; x_{2} = Total Outcomes.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Favorable Outcomes: Used directly in the calculation.
- Total Outcomes: Used directly in the calculation.
