geometric_distribution() : geometric_distribution(0.5) {}	(1)	(since C++11)
explicit geometric_distribution( double p );	(2)	(since C++11)
explicit geometric_distribution( const param_type& params );	(3)	(since C++11)

Constructs a new distribution object.

2) Uses p as the distribution parameter.

3) Uses params as the distribution parameter.

Parameters

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

Notes

Requires that 0 < p < 1.
