WebPermutations. The permutation relationship gives you the number of ways you can choose r objects or events out of a collection of n objects or events. As in all of basic probability, the relationships come from counting the number of ways specific things can happen, and comparing that number to the total number of possibilities. WebThe combinations formula is used to easily find the number of possible different groups of r objects each, which can be formed from the available n different objects.
