Answer 2

The value of $^{50}P_2$ = 2450

Step-by-step explanation:

We have,

$^{50}P_2$

To find, the value of $^{50}P_2$ = ?

∴ $^{50}P_2$

We know that,

$^{n}P_r=\dfrac{n!}{(n-r)!}$

Here, n = 50 and r = 2

$^{50}P_2$

= $\dfrac{50!}{(50-2)!}$

$=\dfrac{50!}{(48)!}$

$=\dfrac{49!\times 49\times 50}{(48)!}$

[ ∵ n! = (n - 1)! × n ]

= 49 × 50

= 2450

∴ The value of $^{50}P_2$ = 2450
