PERMUT(Number,NumberChosen)

• $Number$ and $NumberChosen$ are integers.
  • PERMUT(), returns the number of permutations for a given number of objects.

Description

• This function gives the number of Permutations for a given number of objects.
• A permutation, also called an "arrangement number" or "order", is a rearrangement of the elements of an ordered list.
• A selection of objects in which the order of the objects matters.
• A Permutation is an Ordered Combination.
• In $PERMUT(Number,NumberChosen)$, $Number$ is an integer which is indicating the number of objects and $NumberChosen$ is an integer which is indicating the number of objects in each permutation.
• For $Number$ and $NumberChosen$, when we give in decimals, it will change into integers.
• The formula for the number of permutation is: $_{n}P_{k}={\frac {n!}{(n-k)!}}$
• The Permutation is denoted by $_{n}P_{k}$, $P_{n,k}$, or $P(n,k)$.This function will give the result as error when

1.$Number$ and $NumberChosen$ are non-numeric.
2.Suppose $Number\leq 0$  or  $NumberChosen<0$ or $Number<NumberChosen$.

Examples

1. PERMUT(14,2) = 182
2. PERMUT(50,5) = 254251200
3. PERMUT(10.2,3) = 720
4. PERMUT(4,0) = 1
5. PERMUT(6,1) = 6
6. 34!P!3 = 35904
7. PERMUT(COMBIN(34, 3n), 3) OR a=34n!C!3!P!3 = 214169191104
