Permutation is denoted by P-xA0-Total number of things A-xA0-Number of different things n-xA0-x21D2- Permutation of n different things-xA0-Taken r at a time - nPrHere r is 3Hence- the answer is 3-

Permutation of $n$ different things taken ____ at a time is denoted by ${^{n} P}_{3}$ .

Permutation is denoted by $P$
Total number of things $A$
Number of different things $n$
$\Rightarrow$ Permutation of $n$ different things
Taken $r$ at a time = ${^{n} P}_{r}$
Here $r$ is $3$
Hence, the answer is $3$ .

Permutation of n different things taken ____ at a time is denoted by nP3.

Permutation is denoted by P Total number of things A Number of different things n ⇒ Permutation of n different things Taken r at a time = nPrHere r is 3Hence, the answer is 3.
