Question

Find A ∪ B. (Enter your answers as a comma-separated list.)
A = {2, 4}, B = {0, 1, 2, 3, 4, 5}

Answer 1

I would simply be B
list them as they appear in B

Answer 2

It's a union, so it includes all of A and B. Since the members of A already exist in B, the answer is simply B. Write it out brackets and all, and reap your points.
