Answer
(A∩B) ' = {a,b,c,d,e,f}
Work Step by Step
U = {a,b,c,d,e,f,g,h}
A = {a,g,h}
B = {b,g,h}
C = {b,c,d,e,f}
The set (A∩B)' represents the elements of U which are not present in A∩B.
Since the elements of A∩B should not be present in (A∩B).
A∩B represents the common elements of A and B.
Therefore the common elements of A and B are g,h.
So set A∩B = {g,h}
Therefore set (A∩B) ' contains {a,b,c,d,e,f}.
