Question

Find the value of P (7, 2). HELP PLSSSS

Answer 1

Given:

`P(7,2)`

To find:

The value of the given permutation.

Solution:

Permutation is defined as:

`P(n,r)=(n!)/((n-r)!)`

We have,

`P(7,2)`

Using permutation formula, we get

`P(7,2)=(7!)/((7-2)!)`

`P(7,2)=(7* 6* 5!)/(5!)`

`P(7,2)=7* 6`

`P(7,2)=42`

Therefore, the value of P(7,2) is 42.
