Question

Please HELP! How do I set the combination problem to solve this... Ten students ask to visit a college admissions counselor. Each visit includes one student. In how many ways can five time slots be assigned?

Answer 1

30240

Explanation:

There are 10 possibilities for the first time slot.

After that, there are 9 possibilities for the second time slot.

So on and so forth.

The number of ways five time slots can be assigned is:

10×9×8×7×6 = 30240

Or, using permutation notation, ₁₀P₅.
