## Important Topics for RS Aggarwal Solutions for Class 11 Chapter 1

Defining set, we can say that set is a group of definite numbers or objects which can be considered as a whole within itself. As an example, we can say that ripen bananas in the basket. In this chapter sets and their types are basically explained in detail with their respective questions. The important topic of the chapter Subsets is also explained well.

Important points of the chapter

1. When an object is collected in a well-defined manner, then it forms a set.
2. A set is said to be empty when there is no element.
3. A set that consists of a definite number of elements is called a finite set, otherwise, the set is called an infinite set.
4. Two sets A and B are said to be equal if they have exactly the same elements.
5. The union of two sets A and B is the set of all those elements which are either in A or in B.
6. The intersection of two sets A and B is the set of all elements which are common.
7. For any two sets A and B, (A ∪ B)′ = A′ ∩ B′ and ( A ∩ B )′ = A′ ∪ B′
8.  If A and B are finite sets such that A ∩ B = φ, then n (A ∪ B) = n (A) + n (B). If A ∩ B ≠ φ, then n (A ∪ B) = n (A) + n (B) – n (A ∩ B)
