Question

In how many ways can 8 instructors be assigned to five sections of a course in mathematics?

Answer 1

i believe it would only be:

8*7*6*5*4

Answer 2

When an instructor is picked for the first class, there are 8 people to choose from
For the next class, there are 7 to choose from.
Then 6.
Then 5.
Then 4.

That covers all the classes.
