           & operator<< (std::basic_ostream< _CharT, _Traits > &__os, const std::binomial_distribution<
           _IntType1 > &__x)

       bool operator== (const binomial_distribution &__d1, const binomial_distribution &__d2)
           Return true if two binomial distributions have the same parameters and the sequences that would be
           generated are equal.

           Extracts a binomial_distribution random number distribution __x from the input stream __is.

Detailed Description

   template<typename _IntType = int>                                            n
       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
                                                                                }
