(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}.
