Cumulative distribution function probability
WebIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space).. For instance, if X is used to … WebThe cumulative distribution function of a uniform random variable X is: F ( x) = x − a b − a for two constants a and b such that a < x < b. A graph of the c.d.f. looks like this: F (x) 1 X a b
