Question

If $S=\{2,4,6,8,10,12\}$ and $A=\{4,8,12\}$, find $A^{\prime }$.

Answer 1

$S=$$(2,4,6,8,10,12)$

$A=(4,8,12)$

$A$ is a subset of $S$ as set $S$ contains all the elements of set $A$.

$A^{\prime }$ contains all the elements that are in set $S$ but not in set $A$.

Hence, $A^{\prime }=$$\{2,6,10\}$
