There are 30240 ways in which we can select five people from a group of ten if the order of selection is important.

Given that there are 10 total number of people.

We are required to find the number of ways in which 5 people can be selected from 10 people.

Permutations is basically the number of arrangements that can be possible with the number of things , people, etc. It is denoted as [tex]nP_{r}[/tex]=n!/(n-r)!.

We have 10 people and we have to select 5 people from them then the number of ways can be find out by [tex]10P_{5}[/tex].

We have to expand this permutation.

=10!/(10-5)!

=10!/5!

=10*9*8*7*6*5!/5!

=10*9*8*7*6

=30240 ways

Hence there are 30240 ways in which we can select five people from a group of ten if the order of selection is important.
