Method	Description
Sample ( DiscreteDistribution dist, XorShiftRandom rng ) : int	Sample from the provided discrete probability distribution.
SampleBinaryDistribution ( double probability, XorShiftRandom rng ) : bool	Sample from a binary distribution with the specified probability split between state false and true.
SampleUniformDistribution ( int numberOfOutcomes, XorShiftRandom rng ) : int	Sample from a set of possible outcomes with equal probability, i.e. a uniform discrete distribution.
