If P = {$x$ : $x\,\,\epsilon\,\, W$ and $4 \leq x \leq 8$} and Q = {$x$ : $x \,\,\epsilon\,\, N$ and $x < 6$}.
If $A=\left\{ 2, 4, 6, 8, 10\right\}, B=\left\{1, 3, 5, 7\right\}$ find $(A\cup B)$
if a= all even natural numbers
b=all odd natural number s
Can you say a and b are which type of sets
If $\displaystyle A=\left \{ 2, 3, 5 \right \}, B=\left \{ 2, 5, 6 \right \}$ then  $\left ( A-B \right )\times \left ( A\cap B \right )$ is
