Question

Suppose $U=\{3,4,5,6,7,8,9,10,11,12,13\},A=\{3,4,5,6,9\},B=\{3,7,9,5\}$ and $C=\{6,8,10,12,7\}$. Write down the following set and draw Venn diagram for :
$(A^{\prime }{)}^{\prime }$

Answer 1

$U=\{3,4,5,6,7,8,9,10,11,12,13\}$

$A=\{3,4,5,6,9\}$

$B=\{3,7,9,5\}$

$C=\{6,8,10,12,7\}$

$(A^{\prime }{)}^{\prime }=A$(law of complement)
