Answer 1

$\textbf{concept used:}$

$n_{P_r}\text{=Number of permutations of n things taken r at a time}$

$\textbf{Formula:}$

$n_{P_r}=\displaystyle\frac{n!}{(n-r)!}$

$\text{or}$

$n_{P_r}\text{=n(n-1)(n-2).......r factors}$

$\textbf{Given:}$

$50_{P_2}$

$50_{P_2}=50{\times}49$

$\implies\boxed{\bf\,50_{P_2}=2450}$

$\therefore\text{The value of 50_{P_2} is 2450}$
