juhuliku suuruse X jaotust esitav funktsioon F, mille väärtuseks punktis x on tõenäosus, et juhulik suurus X omandab arvust x väiksema väärtuse
function giving, for every value x, the probability that the random variable X be less than or equal to x
function f of the argument x giving the probability f(x) that the value ξ of a random variable be less than or equal to the value x, i.e. the probability ξ ≤ x
The most common representations of the random variable distribution law are the distribution table, the distribution function, and the distribution density.
