nPr ( <Number n>, <Number r> )
Returns the number of possible permutations without repetition of r elements out of a list of n elements.
Example: nPr(10, 2) yields 90.


CAS Syntax

nPr ( <Number n>, <Number r> )
Returns the number of possible permutations without repetition of r elements out of a list of n elements.
Examples:
  • nPr(10, 2) yields 90.
  • nPr(n, 3) yields \frac{n!}{(n-3)!}.
