Consider an unfair six-sided die where the probability of rolling a “1” is three times the probability of rolling any other value. All other values have the same probability of occurring. Let X be the random variable that takes on values 1 through 6 for our unfair die. Plot the pmf and CDF of X. Determine the mean of X.
