If $A$ and $B$ are any two sets, then $A \cap (A \cup B)$ is equal to
$A$
$B$
${A^c}$
${B^c}$
$A-(A-B)$ is
Let $A=\{1,2,3,4,5,6,7,8,9,10\}$ and $B=\{2,3,5,7\} .$ Find $A \cap B$ and hence show that $A \cap B = B$
Let $A$ and $B$ be two sets in the universal set. Then $A - B$ equals
Using that for any sets $\mathrm{A}$ and $\mathrm{B},$
$A \cap(A \cup B)=A$
If $A, B$ and $C$ are any three sets, then $A - (B \cap C)$ is equal to
