How do you calculate the number of combinations? Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the **formula nCr = n! / r!** *** (n – r)!**, where n represents the total number of items, and r represents the number of items being chosen at a time.
