       class std::binomial_distribution< _IntType >" A discrete binomial random oumber distribution.
                                                                                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.                      t
