The shaded region in the given figure is
$A \cap (B \cup C)$
$A \cup (B \cap C)$
$A \cap (B -C)$
$A -(B \cup C)$
Let $A = \{a, b, c\}, B = \{b, c, d\}, C = \{a, b, d, e\},$ then $A \cap (B \cup C)$ is
If $A$ and $B$ are any two sets, then $A \cap (A \cup B)$ is equal to
Let $A$ and $B$ be subsets of a set $X$. Then
If $A$ and $B$ are disjoint, then $n(A \cup B)$ is equal to
If $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ and $D=\{15,17\} ;$ find
$B \cap D$
