Question 451226: 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′U B′. finding A’, then B’ then find their union.

You can put this solution on YOUR website! A = {22, 24, 26, 28, 30}
A' = {23, 25, 27, 29, 31, 32} .... this is the set of U but excluding everything in A (ie it's everything but set A). So start with U, then delete every element found in A.
B = {23, 24, 25, 28, 29}
B' = {22, 26, 27, 30, 31, 32}
Now union A' and B' to get
A' U B' = {22, 23, 25, 26, 27, 29, 30, 31, 32}
This is just the combination of the two sets (ie dump all the elements from both sets A' and B' into A' U B' and remove any duplicates).
