Hence, acquire a basic understanding of formulas of ‘Permutations and Combinations’ topic in order to obtain exceedingly well scores in your targeted management entrance exams.
In mathematics, it is possible to learn how things can be selected or arranged with permutations and combinations. It is important to know the difference between permutations and combinations.
The difference between them is that permutations is concerned with the order of things to be arranged where as combinations don’t.
Permutation: The number combination of a brief case. For e.g., if 911 is the combination of a lock then their positions cannot be interchanged.
Combination: If John has a bowl of candies of different flavors like strawberry, orange etc., it can be of any order as anyways it is a bowl of candies.
Thus, Permutation is a combination of things where their order matters.
