WebAug 5, 2024 · Probability distribution is the distribution of total probability over a partition S, support of the random variable X. In particular, if X is a discrete random variable, then S is countable. A probability distribution is measured by the (cumulative) distribution function F ( x) defined by F ( x) = P { ω: X ( ω) ⩽ x } , which we simply write as WebCumulative Required. A logical value that determines the form of the function. If cumulative is TRUE, NORMDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function. Remarks If mean or standard_dev is nonnumeric, NORMDIST returns the #VALUE! error value.
