Examples
Try the starting example
- Independent event probabilities
- 0.5,0.5
- All occur
- 0.25
- At least one
- 0.75
Try another scenario
- Independent event probabilities
- 1,1
- All occur
- 1
- At least one
- 1
Calculation method
Calculation method
All occur
Multiply the independent event probabilities.
At least one
Use −expm1(sum(log1p(−p))) to compute one minus the probability that none occurs; an event with probability one makes this result one.
Symbols and units

- Independent event probabilities
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- The product rules here require independent events. Lists support up to 1,000 finite values.
