Two probability distributions are shown in the following tables. For each case, describe a specific setting of random selection (like the one given in Exercise 5.22) that yields the given probability distribution. and three do not. If three candidates are selected at random, find the probability distribution of X, the number having social science degrees among the selected persons.
