What are Combinations?
Combinations represent the number of ways to select items from a larger set where the order doesn't matter. For example, selecting 3 fruits from a basket of 5 fruits, where the sequence of selection is irrelevant.
Formula
The formula for calculating combinations is:
C(n,r) = n! / (r! × (n-r)!)
Where n is the total number of items and r is the number of items being selected.
