What is Permutation and Combination?
Permutation and combination is a branch of mathematics that deals with the study of the arrangement and selection of objects from a set where the order of the objects matters. It is used in counting and determining the number of arrangements and selections. In this article we’ll take a closer look at permutations and combinations and how to solve permutation and combination problems.
What is Permutations?
In mathematics, a permutation is a rearrangement of objects or values. A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For example, 3124 is one possible permutation of the digits 1, 2, 3 and 4. If the order of the arrangement is important, it is a permutation; if not, it is a combination.
What is Combinations?
In mathematics, a combination is a way of selecting items from a collection, such that the order of selection does not matter. For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange.
What is Permutation & Combination Problems?
Permutation & Combination problems are mathematical problems which involve the selection, arrangement and ordering of objects from a given set. These problems are most commonly encountered in probability theory, and are used to calculate the probability of a given event occurring. Permutations and combinations can also be used to solve puzzles and riddles.
How to Solve Permutation & Combination Problems?
The first step in solving a permutation & combination problem is to identify the objects and the number of objects in the set. Once this has been done, the next step is to determine the total number of combinations or permutations that can be created from the set. This can be done by using a combination formula or a permutation formula.
Example of Permutation & Combination Problems
Example 1: Contoh Soal Pilihan Ganda Permutasi Siklis
In this example, you are given a set of five letters: A, B, C, D and E. The question is to find the total number of permutations of these five letters. To solve this, we use the permutation formula to calculate the total number of permutations that can be formed. The answer is 120.
Example 2: Contoh Soal Pilihan Ganda Permutasi Non-Siklis
In this example, you are given a set of six letters: A, B, C, D, E and F. The question is to find the total number of permutations of these six letters. To solve this, we use the permutation formula to calculate the total number of permutations that can be formed. The answer is 720.
Conclusion
Permutation and combination problems are mathematical problems which involve the selection, arrangement and ordering of objects from a given set. Permutations and combinations can be used to calculate the probability of a given event occurring, and to solve puzzles and riddles. The two main types of permutation & combination problems are permutation (where the order of the objects matters) and combination (where the order of the objects does not matter). To solve a permutation & combination problem, the first step is to identify the objects and the number of objects in the set. The second step is to determine the total number of combinations or permutations that can be created from the set. This can be done by using a combination formula or a permutation formula.
