For example, 5! = 5 ⋅ 4 ⋅ 3 ⋅ 2 ⋅ 1. The factorial symbol is used in the formulas for permutations and combinations. Combination Formula: The number of ways to choose k objects from a group of n objects is:

WebSection 3.4 Permutations and Combinations 20 Counting with Repetitions (cont’d) This remapping reduces the problem to “how many possibilities are there to rearrange a sequence containing r 0s and n-11s”. This is a permutation problem with duplicates but without repetitions. The solution to the combination problem with repetitions is: WebPermutation: It is an arrangement of outcomes or objects in which order does matter. Formula: Where ‘n’ indicates, no. of things and ‘r’ indicates no. of things chosen at a time. …
