Let $U$ be the universal set and $A \cup B \cup C = U$. Then $\{ (A - B) \cup (B - C) \cup (C - A)\} '$ is equal to
$A \cup B \cup C$
$A \cup (B \cap C)$
$A \cap B \cap C$
$A \cap (B \cup C)$
Taking the set of natural numbers as the universal set, write down the complements of the following sets:
$\{ x:x$ is a perfect cube $\} $
Draw appropriate Venn diagram for each of the following:
$(A \cup B)^{\prime}$
Draw appropriate Venn diagram for each of the following:
$A^{\prime} \cup B^{\prime}$
If $A$ and $B$ be any two sets, then $(A \cap B)'$ is equal to
If $A$ and $B$ are two sets, then $A \cap (A \cup B)'$ is equal to
