This document provides three probability distributions defined by their moment generating functions (MGFs) and asks to identify the name of each distribution and the value of its parameters based on the given MGFs. The three distributions are: (a) a Poisson distribution with parameter 3, (b) a binomial distribution with parameters 10 and 0.2, and (c) a mixture of an exponential distribution with rate 0.3 and a degenerate distribution with probability 0.7 at value 1.
