The first is 6 sided (X=1,2,3,4,5,6) and the second is 4 sided (Y=1,2,3,4). a. Determine the probability mass function (pmf) of each random variable, separately b. Determine the moment generating function (mgf) of each random variable c. Consider a board game that is played by rolling these two dices at each round and the players move according to the sum of the two dices (Z=X+Y). The possible values of Z are (2,3,4,5,6,7,8,9,10). Use the moment generating functions of these two discrete random variables to find the moment generating function of Z d. Use the mgf of Z to find the probabilities for each of the values of Z (in other words, what is the distribution of Z, or the pmf of Z) e. Use the mgf of Z to find the expected value of Z f. Use the pmf of Z to find the expected value of Z
