This example would be calculated using permutations, since the order of the results matter. It is further classified into four typesrepetitive, non-repetitive, circular, or multisets. Permutation differs from combinations they are two different mathematical techniques. It is a mathematical calculation used for data sets that follow a particular order. How many possible permutations of first, second, and third place be awarded in a race between 10 people? A permutation is the total number of ways a sample population can be arranged. The equation is nCr = (n!)/((n-k)!k!), where n is the number of participants, and k is the number of people we are choosing. This example would be calculated using combinations, since the order of the people being chosen doesn't matter.
