Question

Evaluate P(4, 2) 24 12 6

Answer 1

Answer:

Option (b) is correct

$^4P_2=12$

Step-by-step explanation:

Given: P(4,2)

We have to evaluate the value of P(4,2)

Consider the permutation P(4,2).

The possibility of choosing an ordered set of r object from n object is given by

$^nP_r=\frac{n!}{(n-r)!}$

here, n = 4 and r = 2

Thus,

$^4P_2=\frac{4!}{(4-2)!}$

Simplify, we have,

$^4P_2=\frac{4!}{(2)!}=\frac{4\cdot 3\cdot 2!}{2!}=12$

Thus,  $^4P_2=12$

Answer 2

12 is the answer you are lkkoing for
