ANSWER
A' ∩ B = {2, 4, 8, 10}
EXPLANATION
We want to find A' ∩ B.
First, we have to find A'.
To do that, we will need to find all the elements that are not in the set A but are in the universal set.
We are given that:
A = {1, 3, 5, 7, 9, 11}
W = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
=> A' = {2, 4, 6, 8, 10, 12}
The symbol ∩ means that we want to find ONLY the elements that are in the two sets, A' and B.
Therefore:
A' ∩ B = {2, 4, 8, 10}
