Question 400 of 480
Given U = {1,2,3,4,5,6,7,8,9} and A = {1,3,5,7,9}, what is the complement A′?
- {1,3,5,7,9}
- {2,4,6,8}
- {1,2,3,4,5}
- ∅
Correct Answer:
B
Explanation
The complement of A consists of all elements in U that are not in A. Removing the odd numbers 1-9 from U leaves the even numbers 2-8.
