Detailed Description
A Bernoulli random number distribution.
Generates a sequence of true and false values with likelihood $ p $ that true will come up and $ (1 - p) $ that false will appear.

Constructor & Destructor Documentation
std::tr1::bernoulli_distribution::bernoulli_distribution (double __p = 0.5) [inline, explicit] Constructs a Bernoulli distribution with likelihood p.
Parameters:
__p [IN] The likelihood of a true result being returned. Must be in the interval $ [0, 1] $.
