None of these
Taking the set of natural numbers as the universal set, write down the complements of the following sets:
$\{ x:x$ is an even natural number $\} $
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}) = $
If $A$ and $B$ be any two sets, then $(A \cap B)'$ is equal to
Let $U = \{ 1,\,2,\,3,\,4,\,5,\,6,\,7,\,8,\,9,\,10\} $, $A = \{ 1,\,2,\,5\} ,\,B = \{ 6,\,7\} $, then $A \cap B'$ is
