About Combinations

A combination is a selection of items from a larger set where order doesnt matter. The formula for combinations is:

C(n,r) = n! / (r! * (n-r)!)

Examples

For example, if you want to choose 2 people from a group of 5 people, the calculation would be:

  • C(5,2) = 5! / (2! * (5-2)!)
  • = 120 / (2 * 6)
  • = 10 combinations
