Interface

bernoulli(p:real) : int

where 0.0<=p<=1.0. The value returned is either 0 or 1. The function returns a drawing from a Bernoulli distribution with probability p for success, i.e. success=1.

Raises Bernoulli exception, if p<0.0 or p>1.0.

Characteristics

Mean: p
Variance: p(1-p)

Example

bernoulli(1.0/6.0)

Throw a die and observe if a six was thrown. This experiment has a Bernoulli distribution with parameter p=1/6 for success.
