Question

If A={0,1,2,3,4,5,6,7,8,9,10}, then insert the appropriate symbol or in each of the following blank spaces:
(i) 4 ……A

(ii) -4……A
(iii) 12…..A

(iv) 9…..A
(v) 0……A

(vi) -2……A

Answer 1

Since, the symbol ‘∈’ means belongs to. ‘∉’ means does not belong to.

(i) 4 ……A

4 ∈ A (here, 4 is present in set A)

(ii) -4……A

-4 ∉ A (here, -4 is not present in set A)

(iii) 12…..A

12 ∉ A (here, 12 is not present in set A)

(iv) 9…..A

9 ∈ A (here, 9 is present in set A)

(v) 0……A

0 ∈ A (here, 0 is present in set A)

(vi) -2……A

-2 ∉ A (here, -2 is not present in set A)
