> Hi,
> Unless I am mistaken the HypergeometricDistribution probability method returns NaN for
the following cases :
> HypergeometricDistribution hgd = new HypergeometricDistribution(11,11,1);
> double probIT = hgd.probability(1);
> HypergeometricDistribution hgd = new HypergeometricDistribution(11,11,11);
> double probIT = hgd.probability(11);
> I think it should return 1.0
> Thanks,
> Thomas
