Permutation and Combination

This is the overview lesson of the course on Permutation & Combination. It provides the details of who should take this course. The relevance of this topic in examinations. It is the easiest topic to solve these questions from. It talks about the importance of it being more about the language than math. It is an important relevant topic for engineering student & for MBA students for pattern analysis. The lesson ends by providing a list of the topics that will be covered under this course.​

Overview Of The Course: In Depth Study Of Permutation & Combination

This lesson is the introduction of the course on Permutation & Combination. It begins with the utility of the topic. The number of ways of doing a particular thing is explained in detail. Different cases are explained using examples. The relation between the number of ways & number of elements is established. The "n factorial" concept is explained in detail. The idea is furthered by applying the concept in relevant examples.​

Introduction: The Concept Of 'n' Factorial

This lesson entirely focuses on the Permutation Formula. It begins by providing a recap of the concepts taught in the previous lesson. This lesson focuses on arranging some and not all elements. A smart approach to solving the problems is being introduced. The application of the permutation formula is taught by the use of examples.

Learn The Permutation Formula

In this lesson, the presenter focuses primarily on the Combination formula. She emphasises on the concept of arranging all elements from the list containing different or similar elements. Using a wide range of examples, she leads us to understand the derivation of the formula & its application.

Learn The Combination Formula

This lesson focuses on combining both the concepts that have been covered in the previous lessons. The presenter uses an interesting technique to explain to the students the combination of permutation & combination. She also states the differences between choosing multiplication & addition. She then solves a comprehensive question that covers all the concepts that have been discussed and improves the ability of the viewers to apply these concepts. 

Combining Permutation And Combination

Understand what is Circular Permutation and how arrangements are determined in a circle. Surabhi is explaining the importance of direction and why one must be particular about it. She also elaborates over the difference between Linear and Circular Arrangement and Formula for Circular Permutation. Also, certain special cases are being discussed with the help of examples.

Overview Of Circular Permutation

This lesson focuses on the arrangement of alphabets in a word and deals with the approach in which the questions like this need to be handled. Surabhi has taken up an example and has looked into various cases for it. Thereby the lesson explains the concept of 'De-arrangement' and to make this concept clearer the educator has taken up an example and has depicted the application of the same. Watch out for some twists in the questions.

Understand The Rank Of Word And De-arrangement

This lesson helps you to hold a grip on the lessons which you have completed so far in permutation and combination course. This lesson has few conceptual questions which will be solved by the educator, and some key concepts which you should keep in mind will be highlighted. Viewing this lesson will also be like revising the complete course as the questions and solutions for the same are related to each lesson of this course.

I have tried to simplify one of the toughest chapters in the quant section. This is dreaded because by looking at the questions we know that this question is from this very chapter but the fear steps in.  The primary reason is that the basic concepts are not clear. We have tried to help you identify the sums fundamentally so that you understand which idea  is to be applied in which category of sums. We start with the roots and then move on to problems of linear and circular arrangements.
