Question 191916: Given U = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31}, A = {21, 23, 25, 27, 29}, and
B = {22, 25, 28, 29}. Find A′ U B′.
A={21,23,24,26,27,30,31} Did I do this correctly, if not, can someone show me how to do it? Thanks.
Answer by user_dude2008(1862) (Show Source): You can put this solution on YOUR website!
A' = Everything in U not in A = {22, 24, 26, 28, 30, 31}
B' = Everything in U not in B = {21, 23, 24, 26, 27, 30, 31}
A' U B' = new set from combining A' and B' = {21, 22, 23, 24, 26, 27, 28, 30, 31}
Answer: A' U B' = {21, 22, 23, 24, 26, 27, 28, 30, 31}
