Calculation method
Calculation method
Expected value
Multiply each outcome in a by its paired probability in b, then add the products.
Symbols and units
- a
- Outcomes
- b
- Probabilities
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Probabilities must sum to one. The expected value need not be a possible single outcome. Lists support up to 1,000 finite values.
