What Are Combination Probabilities? Probability is the measure of the chances and possibilities that will return a desired outcome. There are different types of probability and combination is one of its types. So, what are combination probabilities? When we are dealing with arrangement of objects and the order does not matter, then we can use combination probability. The result of this probability shows us the total number of ways objects can be arranged without any defined order. When there is an order to follow, a combination probability is called permutation. The formula to calculate combination probabilities include; C(n,r) = n!/((n-r)!r!) | n! means, n × (n-1) × (n-2) ,..., (n-(n-1)).
