If $A, B$ and $C$ are non-empty sets, then $(A -B) \cup (B -A)$ equals
$(A \cup B) -B$
$A -(A \cap B)$
$(A \cup B) -(A \cap B)$
$(A \cap B) \cup (A \cup B)$
Let $A = \{a, b, c\}, B = \{b, c, d\}, C = \{a, b, d, e\},$ then $A \cap (B \cup C)$ is
If $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ and $D=\{15,17\} ;$ find
$B \cap C$
Using that for any sets $\mathrm{A}$ and $\mathrm{B},$
$A \cup(A \cap B)=A$
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 $X=\{a, b, c, d\}$ and $Y=\{f, b, d, g\},$ find
$Y-X$
