Question

Compute the permutations and combinations. 6 P 4 15 30 360

Answer 1

The answer is c.
6 P 4 = 360

Answer 2

Answer:

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

Step-by-step explanation:

we have to evaluate the permutation

$_4^6\txterm{P}$

The permutation formula can be written as

$_r^n\txterm{P}=\frac{n!}{(n-r)!}$

$_4^6\txterm{P}=\frac{6!}{(6-4)!}=\frac{6!}{2!}$

$=\frac{6\times 5\times 4\times 3\times 2!}{2!}=360$

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