Examples of probability mass function
WebThe conditional probability density function of Y given that X = x is If X and Y are discrete, replacing pdf’s by pmf’s in the above is the conditional probability mass function of Y when X = x. The definition of fY X(y x) parallels that of P(B A), the conditional probability that B will occur, given that A has occurred. 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 …
