The Titan hotel routinely experiences no-shows (people making  reservations and not showing up) during the peak season when the hotel  is always full. No-shows follows the probability distribution given in  the table below:
 No-shows (x) Probability
 0 0.1
 1 0.13
 2 0.31
 3 0.16
 4 0.21
 5 0.09
 In order to lessen the number of vacant rooms, the hotel uses an  overbooking policy through which it accepts three more reservations than  the number of rooms available. On a day when the hotel experiences  fewer than three no-shows, there are not enough rooms for those who have  reservations. The hotels policy is to send these guests to a closely  located competing hotel, at a cost, supported by the Titan hotel, of  $125 per person. If the number of no-shows is more than three, the hotel  has vacant rooms, resulting in an opportunity cost of $50 per person.
 a. Simulate 3000 days of operation to calculate the hotels average daily cost
 due to overbooking and opportunity costs.
 b. Determine the optimal number (0, 1, 2, 3, 4, 5, 6) of rooms that the Titan
 hotel should overbook in order to minimize average daily costs.
