WebThis calculates how many different possible subsets can be made from the larger set. For this calculator, the order of the items chosen in the subset does not matter. Combinations with replacement, also called … Webr = 2 Using the formula given above: Permutation: n P r = (n!) / (n-r)! = (12!) / (12-2)! = 12! / 10! = (12 x 11 x 10! )/ 10! = 132 Combination: n C r = n! r! ( n − r)! 12! 2! ( 12 − 2)! = 12! 2! ( 10)! = 12 × 11 × 10! 2! ( 10)! = 66 Example 2: In a dictionary, if all permutations of the letters of the word AGAIN are arranged in an order. easthorpe hall yorkshire

In this example, you should have 24 * 720, so 17,280 will be your denominator. Divide the factorial of the total by the denominator, as described above: 3,628,800/17,280. WebTable 2 lists all the possibilities. The first choice can be any of the four colors. For each of these 4 first choices there are 3 second choices. Therefore there are 4 x 3 = 12 possibilities.
