Permutation as well as combination are very important parts of a high school mathematics syllabus. It seems that the chapter is quite simple in comparison with other maths chapters. But this is not at all true. If you are unable to comprehend which question is to be worked out by using permutation and which by using combination you will not be able to bag your desired marks.
The basic distinction between permutation and combination is specifying the sequence of the items or variables in the topic. In permutation, you have to concentrate on the formation of the number of items and comprehend which variables are brought several times and will all be at a time. But in combination, the arrangement has no role in solving a probability problem.
Besides mathematics, permutation and combination play a very important role in our practical life also. It may sound shocking that permutation is used by poets to determine the syllables in a line of a poem. Furthermore, permutation is also used to determine the schedules for sports matches.
Whereas combination is used in businesses fur making decisions related to production.
Comparison Chart: Permutation Vs Combination
| Factors | Permutation | Combination |
| Implication | A permutation is nothing but various ways of arranging a group of objects in a proper sequence. | The combination is nothing but various paths of selecting variables or objects from a sect of items without concentration on the sequence. |
| Sequence | It is very important to keep your eye on the order of the objects while arranging them. | Order is not important in combination. |
| Denotes | The systematic arrangement of objects. | The selection of objects without maintaining arrangement. |
| What is this? | It is a bunch of objects arranged in a proper reasonable arrangement. | It arranges objects without following the sequence. |
| Answers | It implies the number of groups that may be created from a group of items. | It implies the number of sects can be chosen from a large number of objects. |
| Origin | From an individual combination, multiple permutations can be made. | From an individual permutation, an individual combination can be made. |
The Definition And Formula Of Permutation:
A permutation is nothing but the various paths of arranging all partners in a batch in a particular sequence. It enables us to reach the probable order or reorder of a group in a different sequence.
The Formula Of Permutation:
The process for calculating the number of probable permutations of n amount of elements and obtained r at a time is:
The Definition And Formula Of Combination:
The combination helps to determine the various ways of making a group by selecting several or entire items from a set in no specific sequence.
The formula for calculating the actual amount of probable combinations of n amount of elements and obtained r at a time is:
What Are The Primary Differences Between Permutation And Combination?
These two concepts often apparently seem identical but they are completely different from one another. The primary differences between these two are as follows:
- A permutation is nothing but a process of organizing a set of objects in various ways with a proper sequence whereas in a combination you need to select objects from a large group and arrange them in small sets without maintaining any order.
- The major factors that are very important in the distinction between permutation and combination are order, placement, and position.
- For arranging things, alphabets, digits, colors, people, etc permutation is utilized but the combination is used regularly while choosing the fineness from a menu, making mix and match of our clothes, etc.
- A single combination can produce multiple permutations but a single permutation can produce only one combination.
