Detailed Description
template<typename_IntType=int>
class std::discrete_distribution< _IntType >"A discrete_distribution random number distribution.
This distribution produces random numbers $ i, 0 i < n $, distributed according to the probability mass
function $ p(i | p_0, ..., p_{n-1}) = p_i $.
Since
C++11
