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. WebFor example, 4! = 4 x 3 x 2 x 1 = 24. Examples of binomial distribution problems: The number of defective/non-defective products in a production run. Yes/No Survey (such as asking 150 people if they watch ABC news). Vote counts for a candidate in an election. The number of successful sales calls. injection for sickle cell
