alleryStart learning →In U = {1, 2, 3, 4}, take A = {1} and B = {2}. Which description is correct?
AOverlap; cover U
BOverlap; do not cover U
CDisjoint; do not cover U
DDisjoint; cover U
Answer & Solution
Correct answer: C. Disjoint; do not cover U
A and B share no element, but their union omits 3 and 4, so they are disjoint without covering U.
