Permutation and Combination Calculator

Permutation and combination calculator is a free online tool used for calculating the number of possible outcomes for the given event. BYJU’S permutation and combination calculator tool is easy to access. Enter the number of permutations and combinations in the input field to get the possible outcomes in the output field.

To recall, the permutation is a process of arranging ‘n’ objects taken ‘r’ at a time. The combination is a process of selecting ‘n’ objects taken ‘r’ at a time. To find the possibilities of the given event, the following formulas are used.

Permutation Formula: P(n, r) = (n!)/((n-r)!)

Combination Formula: C(n, r) = (n!)/(r! (n-r)!)

Substitute the value of n and r to the permutations and combinations.
