**The pictorial representation of sets is called Venn diagram**. The universal set is represented by a rectangular region and its subsets by circles inside the rectangle.

In the above given Venn diagram, \(\text{B}\subseteq \text{A}\,\)and \(\text{A}\subseteq U\) and \(\text{B}\,\subseteq \,U\).

Here,\(\text{A}\subset U\)and \(\text{B}\subseteq U\).

**If, there is no common elements in A and B and both are subsets of universal set, then A and B are called disjoint sets.**
