If $A, B$ and $C$ are non-empty sets, then $(A -B) \cup (B -A)$ equals
$(A \cup B) -B$
$A -(A \cap B)$
$(A \cup B) -(A \cap B)$
$(A \cap B) \cup (A \cup B)$
If $A = \{1, 2, 3, 4, 5\}, B = \{2, 4, 6\}, C = \{3, 4, 6\},$ then $(A \cup B) \cap C$ is
If $X$ and $Y$ are two sets such that $X \cup Y$ has $50$ elements, $X$ has $28$ elements and $Y$ has $32$ elements, how many elements does $X$ $\cap$ $Y$ have?
If $A=\{x \in R:|x|<2\}$ and $B=\{x \in R:|x-2| \geq 3\}$ then
If $A=\{1,2,3,4\}, B=\{3,4,5,6\}, C=\{5,6,7,8\}$ and $D=\{7,8,9,10\} ;$ find
$A \cup C$
State whether each of the following statement is true or false. Justify you answer.
