This page is about a feature that is supported only in GeoGebra 4.2. |
- 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.
- Example:
nPr[10, 2]yields 90.
- Example:
nPr[n, 3]yields n³ - 3n² + 2n.
Note: See also BinomialCoefficient command.
