If $X=\{a, b, c, d\}$ and $Y=\{f, b, d, g\},$ find
$Y-X$
$\{ f,g\} $
$Y-X=\{f, g\}$
If $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ and $D=\{15,17\} ;$ find
$A \cap \left( {B \cup D} \right)$
If $\mathrm{R}$ is the set of real numbers and $\mathrm{Q}$ is the set of rational numbers, then what is $\mathrm{R – Q} ?$
If $A=\{1,2,3,4\}, B=\{3,4,5,6\}, C=\{5,6,7,8\}$ and $D=\{7,8,9,10\} ;$ find
$A \cup B$
If $A, B, C$ are three sets, then $A \cap (B \cup C)$ is equal to
$A \cup B \cup C$
