How do you calculate total number of combinations?
Combination Calculator. In finite mathematics a combination is most typically calculated using the formula C(n,r) = n!/r!(n-r)!. In this formula n represents the total number of items and r represents the number of items to choose. The formula is modified depending on the importance of item order and repeating items in the set of allowed results.
