Use the permutation formula to calculate the number permutations of the set {a, b, c, d} taken two at a time. Also list these permutations.
Prove that the characteristic functions of subsets satisfy the following properties:
Either prove it is true (from the definitions of the set operations) or find a counterexample to show that is false.
