Question

Find the circular permutation for 5 things taken 5 at a time.

Answer 1

It is 4! = 24

Think of it as a row permutation 5! divided by 5 because the circle design makes 5 different row arrangements all the same, et cetera.

Hope this helps :)

Answer 2

24.

Explanation:

We are asked to find the circular permutation for 5 things taken 5 at a time.

We will use circular permutation formula to solve our given problem.

The number of ways to arrange n distinct objects along a fixed circle is :
`P_n=(n-1)!`.

Upon substituting our given values in above formula we will get,

`P_5=(5-1)!`

`P_5=4!`

`P_5=24`

Therefore, circular permutation for 5 things taken 5 at a time is 24.
