What can you say about the sets A and B if we know thata) A ? B = A? ________________b) A ? B = A?________________c) A – B = A?________________d) A ? B = B ? A?________________e) A – B = B – A?

Solution:Step 1:In this question: A and B are the two set are given just we have to analyse the sets.Step 2:It is given that A B = ALet us take an example to show that:A = {1,2,3,4}B = {2,3}So, A B = {1,2,3,4}{2,3}A B = {1,2,3,4} =AGiven statement is correct is B is a subset of A.This can be shown in Venn Diagram. Step 3:It is given that A B = ALet us take an example to show that:B = {1,2,3,4}A = {2,3}So, AB = {2,3} {1,2,3,4}AB = {2,3} =AGiven statement is correct is A is a subset of B.This can be shown in Venn Diagram.
