Draw appropriate Venn diagram for each of the following:
$(A \cup B)^{\prime}$
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:
$\{ x:x$ is a prime number $\} $
If $A$ and $B$ are two sets, then $A \cap (A \cup B)'$ is equal to
$\{ x:x$ is an even natural number $\} $
$\{ x:x$ is a positive multiple of $3\} $
Confusing about what to choose? Our team will schedule a demo shortly.
