Which axioms are we permitted to use in our proofs for 1.1? For example, the 3 axioms of probability measures are (1) P(A) >= 0 for all A, (2) P(\Omega) = 1, (3) If A1, A2, ... are disjoint then P(U Ai) = Sum(P(Ai)). Are there other axioms that we may use? I want to avoid skipping steps.

You should uses the 3 axioms + the definition of the complement to prove those statements.
