Given U = {22, ..., 32}, A = {22, 24, 26, 28, 30}, and B = {23, 24, 25, 28, 29}.

Question

 Given U = {22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32}, A = {22, 24, 26, 28, 30}, and B = {23, 24, 25, 28, 29}.

Find A′ ∩ B′. Do not skip to the answer. Show your work, finding A’, then B’ then find their intersection.

Answer 1

The intersection of sets A and B are the common elements: {24 28}; if A' is the complement of A then A' is {22 25 27 29 31} and B' is {22 26 27 30 31} and the intersection of A' and B' is {22 27 31} assuming A and B are derived from U.
