Final answer:

Permutation is used to calculate the number of ways a news program can be set up with specific news stories in order.


Explanation:

Permutation is needed in this situation because the order of the news stories matters. The total number of ways the program can be set up is calculated as 8P3, using the permutation formula:

8P3 = 8! / (8-3)! = 8 x 7 x 6 = 336 ways.

The director has to choose one lead story, one second story, and one closing story from a pool of eight stories.
