In the permutation formula, the variable \( r \) stands for **the number of objects that are chosen** from a larger set. The formula for permutations is typically expressed as \( P(n, r) \) or \( nPr \), where \( n \) is the total number of objects and \( r \) is the number of objects being chosen.
