Show that if one event A is contained in another event B (i.e., A is a subset of B), then P(A) ≤ P(B). [Hint: For such A and B, A and B A' are disjoint and B = AU (BNA), as can be seen from a Venn diagram.] For general A and B, what does this imply about the relation- ship among P(AB), P(A) and P(A U B)?
