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. Web2. Know the deﬁnition of the probability density function (pdf) and cumulative distribution function (cdf). 3. Be able to explain why we use probability density for continuous random variables. 2 Introduction. We now turn to continuous random variables.
