A player who is streaky will likely deviate from this distribution. In other words a streaky player will have more 0 goal games, less 1 goal games, and more multiple goal games than predicted by the Poisson distribution.

WebStep-by-step explanation. 1. The formula for calculating the moment generating function (MGF) of an exponential distribution with parameter is as follows: M (t) = / ( - t), where t is greater than or equal to. Hence, the MGF of each Xi can be calculated as follows: M (t) = 0 / (0 - t) = 0 for t less than 0.
