WebSo the formula for calculating the number of combinations is the number of permutations/k!. the number of permutations is equal to n!/ (n-k)! so the number of combinations is equal to (n!/ (n-k)!)/k! which is the same thing as n!/ (k!* (n-k)!). So the number of combinations in our example is equal to 5!/ (3!* (5-3)!) >=120/ (6*2) => 120/12 => 10.
