Let AA and BB be two sets defined in the universal set UU .Then Venice diagrams of the given sets are given below

(a) C=(ABˉ)(AˉB)C=(A\cap \bar B) \cup (\bar A \cap B)


C=(ABˉ)(AˉB)C=(A\cap \bar B) \cup (\bar A \cap B)


(b) D=(AB)(AB)D=(A\cap B)\cup (A\cap B) =(AB)=(A\cap B)

D=ABD= A\cap B

(c) The set C=(AB)(AB)C= (A\cup B)-(A\cap B)
