If A and B are two sets such that

Question:

If $A$ and $B$ are two sets such that $A \subset B$, then find:

(i) $A \cap B$

(ii) $A \cup B$

Solution:

From the Venn diagrams given below, we can clearly say that if A and B are two sets such that A⊂B">A⊂BA⊂B, then

(i) Form the given Venn diagram, we can see that  A∩B">A∩BA∩B = A

(ii) Form the given Venn diagram, we can see that  A∪B">A∪BA∪B = B
