Question

Evaluate P(3,3) help please

Answer 1

Answer:

The value of P(3,3) is 6

Step-by-step explanation:

We have to evaluate P(3,3)

As permutation can be calculated by the formula

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

$P(3,3)=_3^3\txterm{P}=\frac{3!}{(3-3)!}$

$=\frac{3!}{0!}=\frac{3!}{1}=3\times 2\times 1=6$

Hence, the value of P(3,3) is 6

Answer 2

$P(n,k)$ where $n=k$ is equal to $n!$

So, $P(3,3)=3!=6$

Generally, $P(n,k)=\dfrac{n!}{(n-k)!}$
