The probability distribution of a binary random variable X, where P(X=1)=p and P(X=0)=1-p. The distribution is named after the Swiss mathematician and physicist Jacques Bernoulli (1654-1705).
The variance of the distribution is calculated using the formula Var(X)=p(1-p).
The distribution is asymmetric to the left (negatively asymmetric) if p>0.5, and asymmetric to the right (positively asymmetric) if p<0.5.
