If $A, B$ and $C$ are any three sets, then $A -(B \cup C)$ is equal to
If $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ and $D=\{15,17\} ;$ find
$A \cap D$
Find the union of each of the following pairs of sets :
$A = \{ x:x$ is a natural number and multiple of $3\} $
$B = \{ x:x$ is a natural number less than $6\} $
The shaded region in given figure is-
If $A$ and $B$ are any two sets, then $A \cap (A \cup B)$ is equal to
