can u plzzz clear the other doubts as well?
i'll be greateful...!!!!!
21aUb is maximum when the two set has no element in common ie disjoint
so u have to take all elements of a as well as b in the set aUb
aUb is minimum when all elements of a is contained in b ie a is a subset of b
so taking the elements of b only will suffice so min.= 6
