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 AUB. Do not skip the answer. show your work finding A then B then find their union.

doesn't matter what U is (as long as it includes both A and B!). You have A and B. Just look for all elements in either set:
A = {22,24,26,28,30}
B = {23,24,25,28,29}
AUB = {23,24,25,26,28,29,30}
