Permutations with Replacement

Definition of Permutations

A permutation is an arrangement of items in a specific order. In mathematics, permutations are used to count the number of ways objects can be ordered or arranged.

Permutations with Replacement

In permutations with replacement, each item can be selected more than once. This differs from permutations without replacement, where each item can only be used once. The concept of replacement expands the number of possible permutations.

Mathematical Formula

The formula for calculating permutations with replacement is given by n^r, where:

• n is the number of items to choose from,
• r is the number of items to be chosen.

The formula represents the total number of ways r items can be chosen from a set of n items with replacement.

How to Use the Calculator

1. Input the Number of Elements (n): Enter the total number of different items available for selection.
2. Enter the Length of Permutation (r): Specify how many items are to be chosen.
3. Calculate: The tool computes the permutations using the n^r formula.
