Question

In how many ways can ten applicants line up for a job interview?

Answer 1

That would be ten factorial, 10!, or 10*9*8*7*6*5*4*3*2*1, which would be 3628800

Answer 2

3,628,800ways

Explanation:

In order to know the number of ways ten applicants line up for a job interview, it means we they will need to rearrange themselves in a number of ways.

For example, given n number or people, the number of ways this n people can rearrange themselves can be done in n factorial way i.e n! ways.

Given 10applicants, this applicants can line up for a job in 10! ways

10! = 10×9×8×7×6×5×4×3×2×1

10! = 3,628,800ways

The applicants can line up for the job in 3,628,800ways
