Consider the experiment of rolling 2 dice resulting in the random variable X.X = {the number of fours showing on the dice}. a) Determine all possible values of X and the probability of occurrence for each of thesevalues (i.e., the pmf of X). Assume that the dice are fair. Show your work or justify youranswer. b) Plot the pmf f ( x ) and the CDF F(x) of X. Clearly label all values (on both axes). c) Determine the mean of X.
