Answer:15 P 4=32,760

Step-by-step explanation:15 P 4=15!(15−4)!=15!11!=15⋅14⋅13⋅12⋅11!11!=15⋅14⋅13⋅12=32,760

Answer: 32760 ways.

Step-by-step explanation:

To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.

Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4

Number of ways to visit these 4 cities = 4!

Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways
