Question

Compute the permutations and combinations.

6 P 4

15
30
360

Answer 1

The answer is c.
6 P 4 = 360

Answer 2

`\text{The value of }_4^6\txterm{P}\text{ is }360`

Explanation:

we have to evaluate the permutation

`_4^6\txterm{P}`

The permutation formula can be written as

`_r^n\txterm{P}=(n!)/((n-r)!)`

`_4^6\txterm{P}=(6!)/((6-4)!)=(6!)/(2!)`

`=(6* 5* 4* 3* 2!)/(2!)=360`

`\text{Hence, the value of }_4^6\txterm{P}\text{ is }360`
