If A={1,5,7} and B={5,7,9}.and U={1,3,5,7,9}. Also,. Then find
{1,5,7,9}
{5,7}
{1,3,9}
{1,3,5,7,9}
As we learnt
DE MORGAN’S LAW -
(A ∩ B)′ = A′ ∪ B′
-
A'={3,9} and B'={1,3} since universal set if given.Thus C'=(A ∩ B)′ = A′ ∪ B′={1,3,9}
Option 1)
{1,5,7,9}
Option 2)
{5,7}
Option 3)
{1,3,9}
Option 4)
{1,3,5,7,9}
