1.Set Theory
easy
Let $U=\{1,2,3,4,5,6,7,8,9,10\}$ and $A=\{1,3,5,7,9\} .$ Find $A^{\prime}$
A
$\{ 2,4,6,8,10\} $
B
$\{ 2,4,6,8,10\} $
C
$\{ 2,4,6,8,10\} $
D
$\{ 2,4,6,8,10\} $
Solution
We note that $2,4,6,8,10$ are the only elements of $U$ which do not belong to $A.$
Hence $A^{\prime}=\{2,4,6,8,10\}$
