Permutations and Combinations


This chapter is divided into five sections. This chapter deals primarily with building logical approach and solving with first principles (Principles of counting). The first section deals with fundamental principles of counting. A logical and step-by-step application of principles of counting has given rise to the subject of Permutations and combinations. The second section deals with Permutations. Permutations is basically about finding different ways of arranging the things, numbers etc. In the third section, we will learn about Combinations. As the name suggests, the Combinations deals with the selection of things, numbers etc. that needs to be arranged in different orders. The fourth section “Applications of Basics” deals with inculcating logical thinking and refrain from memorising the formulae. It concentrates on building logical approach, solving everything from first principles. In the last section, we will work on more advanced concepts of the previously learned topics in this chapter. At the end of this section, we have a series of exercises to test your understanding of this chapter, solved examples, previous years’ IIT JEE questions pertaining to this chapter.
