**Sets class 11 Notes**

**Set – Set is a well defined collection of objects.**

Example 1 – collection of first five even numbers

That is {2, 4, 6, 8, 10}

Example 2 – First 6 Natural Numbers

That is {1, 2, 3, 4, 5. 6}

**Types of Sets:**

**1. Finite sets**

First 3 odd numbers – {1, 3, 5}

Collection of Vowels – {a, e, i, o, u}

**2. Infinite Set**

Collection of odd numbers – {1, 3, 5, 7, 9, 11 , . . .}

Collection of even numbers = {2, 4, 6, 8, . . .}

**3. Equal Sets**

A = {1, 3, 5} , B = {3, 1, 5}

They both are same and hence both are Equal

**4. Equivalent Sets**

If the number of elements in different sets are same/equal then they are called Equivalent Sets.

A = {1, 3, 5} , B = {5, 8, 9}

Number of elements in both the sets are same and hence A,B are called Equivalent sets.

**5. Empty set or Null set**

A = {} or A = Φ (phi)

Those sets which don’t have any elements in them are called Empty set or Null set or Void Set

**6. Singleton set**

Those sets which have only single element are called Singleton set.

A= {3} , B = {7}
