Answer:
The correct answer is D. 360,360.
Step-by-step explanation:
Number of cities as stopovers available for selection for an European tour = 15
A traveler has to select a total of five cities from these the given 15 cities for his tour and order is determined by the travel company.
Therefore the number of ways the traveler plan such a tour is given by ![\left[\begin{array}{ccc}15\\5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D15%5C%5C5%5Cend%7Barray%7D%5Cright%5D)
= 3003.
Now the order of the cities chosen by the travel company is given by 3003 × 5! = 360,360 ways.
