Combination Formula Equation

This image presents the widely used mathematical formula for combinations, written as nCr = n! / (r!(n-r)!). This formula is crucial in fields like combinatorics, probability, and statistics, helping to calculate the number of ways to choose 'r' items from a set of 'n' distinct items without regard to the order of selection. The '!' symbol denotes the factorial operation, which is the product of all positive integers up to that number.
