Formula
P(A∪B)=P(A)+P(B)−P(A∩B)
Find chance say at least one of two events go happen.
Example wey show the calculation
- P(A) (%)
- 30
- P(B) (%)
- 40
- Chance of A and B together, P(A and B) (%)
- 10
- Chance of A or B happening
- 60 %
Where e fit work and limits
Use consistent units. Result follow the assumptions wey you enter.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
