# DistFunc_dBinomial¶

DistFunc_dBinomial(n, p, k)

Probability function of a binomial distribution.

Parameters
nint,

The number of trials

pfloat,

The success probability of each trial

kint

The number of success.

Returns
probabilityfloat

The probability to get successes.

Notes

This method implements Loader’s algorithm, the fast and accurate method described in [loader2000], with the further improvements mentioned in [dimitriadis2016].

Examples

>>> import openturns as ot
>>> p = ot.DistFunc.dBinomial(5, 0.2, 2)
