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 nc is an integer which is indicating the number of objects in each permutation.
  • For n and nc ,when we are giving in to decimals it will change in to integers.
  • The formula for the number of permutation is:
  • The Permutation is denoted by _nP_k, P_{n,k}, or P(n,k).This function will give the result as error when
1.n and nc are nonnumeric.
2.Suppose n<=0 or nc<0 or n<nc.

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
