A = {1, 3, 5} and B = {x : x is an odd natural number less than 6}. What is the relationship?
AA ⊂ B but B ⊄ A
BA = B (each is a subset of the other)
CB ⊂ A but A ⊄ B
DA and B are disjoint
Answer & Solution
Correct answer: B. A = B (each is a subset of the other)
B = {1, 3, 5} = A. Hence A ⊂ B and B ⊂ A, giving A = B (the double-inclusion definition of equality).
