Formula for Permutation with Replacement
The formula for calculating permutations with replacement, often denoted as P(n, r) with repetition, is:
P(n, r) = nr
Where:
- n = the total number of distinct items available to choose from.
- r = the number of items to choose, with replacement, from the set.
