                      12. If a letter is selected at random from the word ‘‘Mississippi,’’ find the
                           probability that it is an ‘‘s.’’

                      13. When a die is rolled, the probability of getting an 8 is

                      14. In a survey of 180 people, 74 were over the age of 64. If a person
                           is selected at random, what is the probability that the person is
                           over 64?

                      15. In a classroom of 24 students, there were 20 freshmen. If a student is
                           selected at random, what is the probability that the student is not a
                           freshman?
