Let A = {1, 2, 3} and B = {3, 4} and let the universal set U = {x|x ∈ Z ∧ x ≥ 0}.
1. What is the cardinality of A and cardinality of B.
2. What is the cartesian product A × B.
3. Calculate P(A)
4. Calculate A ∩ B, A ∪ B, A - B
5. Calculate A^c and write in two different ways (set of elements, and then with a set builder).
6. Calculate U - A and compare to A^c.
