If U = {1, 2, 3, 4, 5}, A = {2, 3, 4} and B = {1, 3, 5} then (A ∪ B)’ = _____?
If U = {1, 2, 3, 4, 5}, A = {2, 3, 4} and B = {1, 3, 5} then (A ∪ B)’ = _____?
Explanation
To find (A ∪ B)':
First, find A ∪ B:
A ∪ B = {2, 3, 4} ∪ {1, 3, 5}
= {1, 2, 3, 4, 5}
Now, find the complement of A ∪ B:
(A ∪ B)' = U - (A ∪ B)
= {1, 2, 3, 4, 5} - {1, 2, 3, 4, 5}
