4. ABC hotel in Ottawa has 20 rooms. Based on the past date, the hotel man- ager estimates t 15% chancre of any confirmed reservation is "no-show." Consequently, the hotel would like accept more confirmed reservations than 20, say, 25. If more con- firmed guests arrive th there are rooms, the overbooked guests are sent to another hotel and given a compliment dinner. Suppose that the hotel currently has 25 confirmed reservations.
