Let U = {1, 2, 3,4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4}, B = {2, 4, 6, 8} and C = {3, 4, 5, 6}. Find (B-C)'.

Let U = {1, 2, 3,4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4}, B = {2, 4, 6, 8}

1.	Let U = {1, 2, 3,4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4}, B = {2, 4, 6, 8} and C = {3, 4, 5, 6}. Find (B-C)'.
Answer» If U = {1, 2, 3,4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4}, B = {2, 4, 6, 8} and C = {3, 4, 5, 6} then ( B - C )' ={1, 3, 4, 5, 6, 7, 9} A set is a distinct collection of objects and elements that can be represented in a roaster form or set builder form.
