                                    13. When a die is rolled, the probability of getting an odd number less
                                        than three is

                                    14. A survey conducted at a local restaurant found that 18 people pre-
                                        ferred orange juice, 12 people preferred grapefruit juice, and 6 people
                                        preferred apple juice with their breakfasts. If a person is selected at
                                        random, the probability that the person will select apple juice is

                                    15. During a sale at a men’s store, 16 white sweaters, 3 red sweaters,
                                        9 blue sweaters, and 7 yellow sweaters were purchased. If a customer
                                        is selected at random, find the probability that the customer pur-
                                        chased a yellow or a white sweater.
