Answer

(A∩B)' = {2,4,5,6,7}

Work Step by Step

U = {1,2,3,4,5,6,7} A = { 1,3,5,7} B = {1,2,3} 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 1,3. So set A∩B = {1,3} Therefore set (A∩B) ' contains {2,4,5,6,7}.
