PERMUT(n,nc)


  • and are integers

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 , is an integer which is indicating the number of objects and is an integer which is indicating the number of objects in each permutation.
  • For and , when we give in decimals, it will change into integers.
  • The formula for the number of permutation is:
  • The Permutation is denoted by , , or .This function will give the result as error when
1. and  are non-numeric.
2.Suppose   or   or .

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
