Question

Given two sets $P$ and $Q$ such that
$P=\{x:x\text{is a natural number between}10and16\}$
$Q=\{y:y\text{is even number between}8and16\}$
Find $Q-P$

• A. $\{8,9,10\}$
• B. $\left\{10\right\}$
• C. $\{11,12,13\}$
• D. None of the above

Answer 1

The correct option is B $\left\{10\right\}$

Since, $P=\{11,12,13,14,15\}$ and $Q=\{10,12,14\}$

Thus,

$Q-P=Q-Q\cap P=\left\{10\right\}$.
