The shaded region in the given figure is
$A \cap (B \cup C)$
$A \cup (B \cap C)$
$A \cap (B -C)$
$A -(B \cup C)$
If $A$ and $B$ are any two sets, then $A \cap (A \cup B)$ is equal to
Let $A=\{a, b\}, B=\{a, b, c\} .$ Is $A \subset B \,?$ What is $A \cup B \,?$
If $A$ and $B$ are disjoint, then $n(A \cup B)$ is equal to
If $A, B, C$ are three sets, then $A \cap (B \cup C)$ is equal to
Let $A$ and $B$ be two sets in the universal set. Then $A - B$ equals
