Let $A$ and $B$ be two sets then $(A \cup B)' \cup (A' \cap B)$ is equal to
$A'$
$A$
$B'$
None of these
Draw appropriate Venn diagram for each of the following:
$A^{\prime} \cap B^{\prime}$
If $n(U)$ = $600$ , $n(A)$ = $100$ , $n(B)$ = $200$ and $n(A \cap B )$ = $50$, then $n(\bar A \cap \bar B )$ is
($U$ is universal set and $A$ and $B$ are subsets of $U$)
Taking the set of natural numbers as the universal set, write down the complements of the following sets:
$\{x: x+5=8\}$
Fill in the blanks to make each of the following a true statement :
${{\mathop{\rm U}\nolimits} ^\prime } \cap A = \ldots $
If $A$ and $B$ are two sets, then $A \cap (A \cup B)'$ is equal to
