NCERT Solutions for Class 11 Maths Chapter 1 Sets: Set is a welldefined collection of objects. In our daily life, we use sets in many situations. In arranging books in a shelf we categorize it into different sets, such as a set of novels, a set of short stories, a set of science fictions, etc. In NCERT Solutions for Class 11 Maths Chapter, 1 Set introduces the concept of sets and operations on set. Let's consider an example of a survey in which 5 data are taken. 1. Gender 2. Age 3. weight. 4. waist diameter 5. Diabatic patient or not. Based on the obtained data two main sets are formed the namely diabetic patient and nondiabatic patient. Using these data we will be able to predict whether a new person in the given region will have diabetes or not. So the NCERT Solutions for Class 11 Maths Chapter 1 Sets is the basics of data analysis. The new technology of machine learning uses data for predictions and classifications. (More the data available more accurate will be the prediction). The NCERT Solutions for Class 11 Maths Chapter 1 is the basic unit for the Further Mathematics course.

A brief summary of NCERT Solutions for Class 11 Maths Chapter 1 Sets are given below:
Another important concept of NCERT Solutions for Class 11 Maths Chapter 1 is operations on sets. The Venn diagrams for basic operations are shown below
1. U represents universal sets, A and B represents sets A and B respectively
2. Union of A and B is represented by the green colour. Denoted by :
3. The intersection of set a and B is represented by green colour. Denoted by
4. AB: A but not B. AB is represented by red colour
We can solve many problems using operations on Sets. An example from NCERT Solutions for Class 11 Maths Chapter 1 Sets is given below.
Q) In a class of 35 students, 24 like to play cricket and 16 like to play football. Also, each student likes to play at least one of the two games. How many students like to play both cricket and football?
Solution: Total number of students in class 35.
Number of students like to play cricket: n(c)=24
Number of students like to play football: n(f)= 16
35=n(c)+n(f)Number of students like to play both cricket and football
therefor Number of students like to play both cricket and football=4035=5
This can be represented by a Venn diagram as follows
