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 are giving in to decimals it will change in to integers.
  • The formula for the number of permutation is: 
  • The Permutation is denoted by  , Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle P_{n,k}} , or Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle P(n,k) } .This function will give the result as error when

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
