If $A, B$ and $C$ are non-empty sets, then $(A -B) \cup (B -A)$ equals
$(A \cup B) -B$
$A -(A \cap B)$
$(A \cup B) -(A \cap B)$
$(A \cap B) \cup (A \cup B)$
(c) $(A -B) \cup (B -A) = (A \cup B) -(A \cap B).$
Which of the following pairs of sets are disjoint
$\{a, e, i, o, u\}$ and $\{c, d, e, f\}$
$\{ x:x$ is an even integer $\} $ and $\{ x:x$ is an odd integer $\} $
If $A=\{3,6,9,12,15,18,21\}, B=\{4,8,12,16,20\},$ $C=\{2,4,6,8,10,12,14,16\}, D=\{5,10,15,20\} ;$ find
$B-A$
If ${N_a} = [an:n \in N\} ,$ then ${N_5} \cap {N_7} = $
Find the union of each of the following pairs of sets :
$A = \{ x:x$ is a natural number and $1\, < \,x\, \le \,6\} $
$B = \{ x:x$ is a natural number and $6\, < \,x\, < \,10\} $
