Description

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
