How do you do nCr?

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