Let U = {0, 1, 2, 3, 4, 5,...}, A = {1, 2, 3, 4,...}, B = {4, 8, 12, 16,...}, and C = {2, 4, 6, 8,...}. Determine the following:

  1. Given
    U = {0, 1, 2, 3, 4, 5,...},
    A = { 1, 2, 3, 4,...}
    where U is the universal set, then
    A'=complement of A
    = U-A
    and A' contains all elements that are in U but not in A, namely
    A'={0}
    Since C={2,4,6,8...} and does not contain 0, so we conclude that
    A' ∩ C = ∅
