Show A-B and B-A by Venn diagrams when

**(i) A and B are overlapping sets**

SOLUTION:

A and B are overlapping sets,then the shaded region in fig(1) represents A-B. The shaded region in fig(2) represents B-A.

**(ii) A⊆B **

SOLUTION:

If A is a subset of B then the set A will be contained in B.There is no shaded region in fig(1) to represent (A-B).The shaded region in fig(2) represents (B-A).

**(iii) B⊆A**

SOLUTION:

If B is subset of A,then the set B will be contained in A.The shaded region in fig(1) represents A-B. There is no shaded region in Fig(2) to represent B-A.
