If $P = \{1, 2, 3, 4, 6, 12\}$ and $Q = \{3, 6, 9, 12\}$ , then $P - Q =$

a $\{3, 6, 12\}$
b $\{1, 2, 4\}$
c $\{9\}$
d $\{1, 2, 3, 4\}$

ব্যাখ্যা

$P - Q$ keeps only those members of $P$ absent from $Q$ ; the shared elements $3$ , $6$ , and $12$ are removed, leaving $\{1, 2, 4\}$ . Note that $9 \in Q$ but $9 \notin P$ , so it never appears.
