This note helps you learn about the branch of mathematics in which the topics Permutation and Combinations lie.For the basic concept of the problems we solve using permutation and combination, we learn here about the basic principle of counting.
The note gives a knowledge on permutation. It teaches you how to denote permutation in symbol, finding the permutation using factorial notation, different cases of permutation and solving some problems.
This note gives you the idea about circular and restricted permutation and solve the problems related to them.
This note helps us learn about the difference in permutation and combination.This note also teaches us how to denote combination for any given number of objects or things and find it using factorial notation.
