![]() We hope the examples shared in this write-up have enlightened you on how we practice our knowledge of permutation and combination to make our lives easier. ![]() Real-life examples clarify our doubts and show how we use our learnings in daily life. And that’s simply because we learned them in school. We just fail to appreciate why we’re able to do it. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. We use our knowledge in so many ways regularly. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. When learning topics like permutation and combination, students often think they will never use them later in life. for example, if we have a set with 20 elements, the permutation would allows us to find the number of ways we can select a determined number of elements. The combination of dishes we select gives us a great dining experience. Our sequence of selection does not alter the taste of the food. While doing so, we pick items from the menu in random order and place our order. So, what do we do? We select the best possible combination of foods to satiate our taste buds. For example, there are six permutations of the set. Define and characterize: a) Permutations from n elements b) Permutations from n elements with repetition Solution: Permutations A pemutation is a sequence containing each element from a finite set of n elements once, and only once. There’s so much deliciousness on the menu which leaves us confused. Informally, a permutation of a set of objects is an arrangement of those objects into a particular order. Permutations examples of problems with solutions Permutations 1. Ordering food at a restaurant is never easy. So, keep reading! Real-life examples of permutations 1. We have jotted down some interesting examples in this write-up to help you understand how these math concepts find their way into the real world. On the contrary, combination involves arranging or selecting objects/ data from a large set, and the arrangement or order of selection does not matter. An important point to remember here is that the order of arrangement of objects/ data matters in permutation. Permutation involves arranging a set of objects or data in sequential order and determining the number of ways it can be arranged. Example 8.1.3: Suppose that we have a set of five distinct objects and that we wish to describe the permutation that places the first item into the second position, the second item into the fifth position, the third item into the first position, the fourth item into the third position, and the fifth item into the fourth position. But what exactly are they? While both terms are used together, they are not the same. There are several real-life situations where we use the knowledge we have learned in school about permutation and combination. Would you believe it if we said that while playing the piano or making a cup of coffee, you’re unknowingly applying mathematical concepts of permutation and combination? Most definitely not.
