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 density must be constant over the interval (zero outside), and the distribution function increases linearly with t in the interval. Thus, fX(t) = 1 b − a ( a < t < b) (zero outside the …
