if n(A)=80 and n(B) then find the minimum value of n(A U B)?

Question: If n(A)=80 and n(B) =60 then find the following:-
i. The minimum value of n(A U B)
ii. The maximum value of n(A U B)
Solution:
Given n(A) = 80, & n(B) =60
i. The minimum value of n(A U B)
Thus for a Union of A & B i.e. A U B, all the elements of set A & B should be added
