Question

Let the universal set U = {1,2,3,4,5, 6, 7) , also A = {2,4,5,6) , B = {1,4,6) and C = {3,4,5) . Use
this information to answer each of the following:
C. (4uB)'=

Bot · Answer

The complement of B is {1,2,3,5,7} (since it contains all elements not in B from the universal set U). Therefore, the union of {4} and the complement of B is {4,1,2,3,5,7}. So (4uB)' = {1,2,3,5,7}.
