How do you find out how many possible combinations there are?

Looking at the equation to calculate combinations, you can see that factorials are used throughout the formula. Remember, the formula to calculate combinations is nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

What is the counting rule for combinations?

Summary. The Fundamental Counting Principle states that if one event has m possible outcomes and a 2nd event has n possible outcomes, then there are m⋅n total possible outcomes for the two events together. A combination is the number of ways of choosing k objects from a total of n objects (order does not matter).
