Permutation and Combination Calculator


All possible arrangements of a grouping of things, where the order is important is called permutation. A Grouping of things, in which the order does not matter is called Combination. Given Calculator finds the Permutation and combination of the given numbers. Calculates the given value uing following formula :
Permutation: nPr = n! / (n-r)!
Combination: nCr = nPr / r!
Number of sample points in set n :
Number of sample points r :
