If $A$ and $B$ be any two sets, then $(A \cap B)'$ is equal to
Draw appropriate Venn diagram for each of the following:
$(A \cap B)^{\prime}$
Let $n(U) = 700,\,n(A) = 200,\,n(B) = 300$ and $n(A \cap B) = 100,$ then $n({A^c} \cap {B^c}) = $
Given $n(U) = 20$, $n(A) = 12$, $n(B) = 9$, $n(A \cap B) = 4$, where $U$ is the universal set, $A$ and $B$ are subsets of $U$, then $n({(A \cup B)^C}) = $
Fill in the blanks to make each of the following a true statement :
${{\mathop{\rm U}\nolimits} ^\prime } \cap A = \ldots $
