How to calculate the number of possible combinations?

To calculate combinations (where order doesn't matter), use the formula C(n, r) = n! / [r! * (n - r)!], where 'n' is the total items, 'r' is items chosen, and '!' is factorial, meaning you multiply the number by all positive integers below it (e.g., 4! = 4x3x2x1). This formula finds distinct groups, like picking 2 books (r) from 8 (n) by solving 8! / (2! * 6!) = 28 ways, by dividing permutations by the ways the chosen items can be arranged.
