If $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ and $D=\{15,17\} ;$ find
$A \cap D$
$A \cap D=\varnothing$
Show that the following four conditions are equivalent:
$(i)A \subset B\,\,\,({\rm{ ii }})A – B = \phi \quad (iii)A \cup B = B\quad (iv)A \cap B = A$
Let $V =\{a, e, i, o, u\}$ and $B =\{a, i, k, u\} .$ Find $V – B$ and $B – V$
If $A, B$ and $C$ are any three sets, then $A – (B \cap C)$ is equal to
If $A$ and $B$ are two sets then $(A -B) \cup (B -A) \cup (A \cap B)$ is equal to
$A \cap \left( {B \cup C} \right)$
