Question

If $U=\{x|x\le 25,xϵN\},A=\{x|xϵU,x\le 15\}$ and $B=\{x|xϵU,0<x\le 25\}$, list the elements of the following sets and draw Venn diagram:
$B^{\prime }$ in $U$

Answer 1

$U=\{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25\}$

$A=\{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15\}$

$B=\{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25\}$

$B=U$

$B^{\prime }=\varphi$
