# Let A = {1, 2, 3, 4, 5, 6}. Insert the appropriate symbol ∈ or ∉ in the blank spaces:

(i) 5. . .A (ii) 8 . . . A (iii) 0. . .A

(iv) 4. . . A (v) 2. . .A (vi) 10. . .A

**Solution:**

Let us understand the meanings of ∈ and ∉.

'∈' is read as "belongs to". If an element 'a' is present in a set 'A', then we say that a ∈ A.

'∉ is read as "does not belong to". If an element 'a' is NOT present in a set 'A', then we say that a ∉ A.

**Accordingly,**

**(i) **5 ∈ A as 5 is present in set A.

**(ii)** 8 ∉ A as 8 is NOT present in set A.

**(iii)** 0 ∉ A as 0 is NOT present in set A.

**(iv)** 4 ∈ A as 4 is present in set A.

**(v)** 2 ∈ A as 2 is present in set A.

**(vi)** 10 ∉ A as 10 is NOT present in set A.

## Let A = {1, 2, 3, 4, 5, 6}. Insert the appropriate symbol ∈ or ∉ in the blank spaces: (i) 5. . .A (ii) 8 . . . A (iii) 0. . .A (iv) 4. . . A (v) 2. . .A (vi) 10. . .A

**Summary:**

A = {1, 2, 3, 4, 5, 6} is given. We have inserted the appropriate symbol ∈ or ∉ in the blank spaces as follows:

**(i) **5 ∈ A **(ii)** 8 ∉ A **(iii)** 0 ∉ A **(iv)** 4 ∈ A **(v)** 2 ∈ A **(vi)** 10 ∉ A.
