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}.
