Inserts a binomial_distribution random number distribution __x into the output stream __os.
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>
class std::binomial_distribution< _IntType >" A discrete binomial random number distribution. The formula for the binomial probability density function is $p(i|t,p) = n} p^i (1 - p)^{t - i}$ where $t$ and $p$ are the parameters of the distribution.
