binomial_distribution() : binomial_distribution(1) {}	(1)	(since C++11)
explicit binomial_distribution( IntType t, double p = 0.5 );	(2)	(since C++11)
explicit binomial_distribution( const param_type& params );	(3)	(since C++11)

Constructs a new distribution object.

2) Uses t and p as the distribution parameters.

3) Uses params as the distribution parameter.

Parameters

t	-	the t distribution parameter (number of trials)
p	-	the p distribution parameter (probability of a trial generating true)
params	-	the distribution parameter set

Notes

Requires that 0 ≤ p ≤ 1 and 0 ≤ t.
