Question 436119:  The 2003 Zagat Restaurant Survey provides food, décor, and service ratings for some of the top restaurants											
across the United States.  For 15 top-ranked restaurants located in Boston, the average price of a dinner											
including, one drink and tip, was $48.60.  You are leaving for a business trip to Boston and will eat dinner at 											
three of these restaurants.  Your company will reimburse you for a maximum of $50 per dinner.  Business 											
associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants											
will exceed $50.  Suppose that you randomly select three restaurants for dinner.											
											
a.  What is the probability that none of the meals will exceed the cost covered by your company?											
b.  What is the probability that one of the meals will exceed the cost covered by your company?											
c.  What is the probability that two of the meals will exceed the cost covered by your company?											
d.  What is the probability that all three of the meals will exceed the cost covered by your company?

 Since the problem states that you will eat at 3 of these restaurants then there is no replacement.
5 restaurants' meals are over $50. and 10 are not.
a)10C3/15C3 = 120/455 = .2637
b)(10C2 * 5C1)/15C3 = 225/455 = .4945
c)(10C1 * 5C2)/15C3 = 100/455 = .2198
d) 5C3/15C3 = 10/455 = .0220
