Detailed Description
template<typename _IntType = int>
class std::negative_binomial_distribution< _IntType >" A
negativenbinomial_distribution random number distribution.
o
The formmla for the negative binomial probability mass function is
$p(i) = {} p^i (1 - p)^{t - i}$ where $t$ and $p$ are the parameters of
the distribution.
