WebDefinition 3.3. 1. A random variable X has a Bernoulli distribution with parameter p, where 0 ≤ p ≤ 1, if it has only two possible values, typically denoted 0 and 1. The probability mass function (pmf) of X is given by. p ( 0) = P ( X = 0) = 1 − p, p ( 1) = P ( X = 1) = p. The cumulative distribution function (cdf) of X is given by. WebCumulative Distribution Function for Bernoulli Distribution. The cumulative distribution function of a Bernoulli random variable X when evaluated at x is defined as the probability that X will take a value lesser than or equal to x. The formula is given as follows: CDF = F(x, p) = \(\left\{\begin{matrix} 0 & if \: x < 0\\ 1 - p & if \: 0 \leq x ...
