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. Web$$p(1) = P(X=1) = P(\{ht, th\}) = 0.5.\notag$$ Similarly, we find the pmf for \(X\) at the other possible values of the random variable: \begin{align*} p(0) &= P(X=0) = P(\{tt\}) = 0.25 \\ … We would like to show you a description here but the site won’t allow us.
