Given U = {15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25}, A = {16, 18, 20, 22}, and B = {17, 19, 20, 23, 24}. Show your work, finding A’, then B’ then find their intersection.
Hint:
A' contains all elements in U but not in A, so
A'={15,17...25}
Similarly,
B'={15,16,18...25}
A'∩B' contains only elements that are present in both A' and B', so
A'∩B'={15,....25}
Complete the sets and post your answers for a check if you wish.
