POISSON DISTRIBUTION USING MOMENT GENERATING FUNCTIONS

Moment generating functions If X is a random variable, then its moment generating function is Recall that                                                                                             Exponential series Therefore, expectation of X (Ex) = For poisson Thanks for reading, for complain or suggestion you can comment or send me private message.
