      54. This problem involves the use of the Binomial distribution since we have two possible outcomes – either you go to court or you do not. Our original distribution is Binomial with the probability of going to court being 0.40 and the probability of not going is 0.60. We will let X equal the number of times we go to court in n = 50 cases.
