The CDF defined for a discrete random variable and is given as Fx(x) = P(X ≤ x) Where X is the probability that takes a value less than or equal to x and that lies in the semi-closed interval (a,b], where a < b. Therefore the probability within the interval is written as P(a < X ≤ b) = Fx(b) – Fx(a) The CDF defined for a … See more The Cumulative Distribution Function (CDF), of a real-valued random variable X, evaluated at x, is the probability function that X will take a value less than or equal to x. It is used to … See more The cumulative distribution function Fx(x) ofa random variable has the following important properties: 1. Every CDF Fxis non decreasing and right continuous limx→-∞Fx(x) = 0 and limx→+∞Fx(x) = 1 1.
