The Town-Pump service station has performed an analysis of its customers and found that 85% pay on credit and the rest pay cash. We are interested in finding the probability distribution of the random variable, X, when X is defined as the number of cash paying customers when four customers are selected at random. That is, find each of the probability of X=0, X=1, X=2, and X=3 under the conditions given by constructing a trials table similar to those constructed in class.
