Answer:
Formulas of Sets
n(P U Q) represents the number of elements present in one of the sets P or Q. n(P ⋂ Q) represents the number of elements present in both the sets P & Q. n(P U Q) = n(P) + (n(Q) – n (P ⋂ Q)

Answer:
In Mathematics, Topic sets, relation, and function is one of the very important topics as this topic serves as a basic building for whole calculus (differential and integral). Every year you will get at max 1 - 2 questions in JEE Main and other exams, directly (as chapter weight in jee main is only 5%) but indirectly, the concept of this chapter will be involved in whole calculus, differential and integral both part and function will be used in many other chapters. Sets, relations, and functions are building blocks for calculus and hence a very important chapter in the preparation of competitive entrance exams. Some students find Sets, relation and function little challenging to understand and solve the problems initially. But as you solve more and more problems on the Sets, relation and function you will get familiar with this topic. Afterward, the questions will appear easy for you. You will find sets little easy compared to relation and function, the concept of sets will be easy to visualize as you can understand them with the help of diagram (Venn diagram). All three topics of this Sets, relation and function are interrelated and earlier concepts of the chapter will be pre-requisite for the latter concept, like sets for relation and relation for function. Overall this chapter will be a little longer than other chapters.
