Detailed Description

   template<typename _IntType = int>class std::binomial_distribution< _IntType >n
       A discrete binomial random number distribution.                          o
                                                                                m
       The formula for the binomial probability density function is $p(i|t,p) = {} p^i (1 - p)^{t
       - i}$ where $t$ and $p$ are the parameters of the distribution.          n
