Distribution function of x

WebDefinition \(\PageIndex{1}\) The probability mass function (pmf) (or frequency function) of a discrete random variable \(X\) assigns probabilities to the possible values of the random variable.More specifically, if \(x_1, x_2, \ldots\) denote the possible values of a random variable \(X\), then the probability mass function is denoted as \(p\) and we write WebJul 13, 2024 · The probability distribution function of a random variable X is given by f ( x). Usually "probability distribution function", if that term is used, means the cumulative distribution function (c.d.f.), often denoted by (capital) F, so that you have Pr ( X ≤ x) = F ( x), and indeed you wrote Pr ( X ≤ x) = f ( x), suggesting that you intended ...
