Formula
P(X=k)=C(K,k)C(N−K,n−k)/C(N,n)
Calculate success counts when you draw samples without putting items back.
Example wey show the calculation
- All items for population N
- 20
- Successful items for population K
- 7
- Number of items wey you draw n
- 5
- Successful items wey you draw k
- 2
- Success count na exactly k
- 38.7383900929 %
- Successes wey you expect on average
- 1.75
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.
