Answer
A'∩B = {2,5,6}
Work Step by Step
A'∩B
A'
The set A' contains all the elements of U that are not in set A.
From the given Venn Diagram III and IV region represents the given set A.
A' = {2,5,6,8,9}
The set A'∩B represents all the common elements of both the sets A' and B.
From the Venn diagram, region III will represent common portion of both the sets A' and B.
A'∩B = {2,5,6}
