Question

9. If U = {1,2,3,4,5,6,7,8,9), A = {2,4,6,8} and B = {2,3,5,7), then
(1 Point)
A' - B' is equal to
{1,3,5,7,9)
{3,5,7,9)
{1,3,5,7)
{3,5,7)

Answer 1

Given :-

$\sf{ U=}${$\sf{1,2,3,4,5,6,7,8,9}$}

$\sf{ A=}${${2,4,6,8}$}

$\sf{ B=}${${2,3,5,7}$}

To Find :-

$\sf{A'-B'}$

Solution :-

$\tt{A'\:=\:}${${1,3,5,7,9}$}

$\tt{B'\:=\:}${${1,4,6,8,9}$}

.

$\tt{A'-B'\:=\:}${$\tt{3,5,7}$}
