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)?

John Wallis and other 17th century mathematicians were struggling with how to fit negative numbers into arithmetic without introducing inconsistencies. Explain the reasoning leading to Wallis's paradoxical claim that, if negative numbers are less than zero, they must be greater than infinity. Wallis's argument depends, in part, on the assertion that (3/-1) = -3. Must this be true? Why or why not? If a student proposed Wallis's argument, how would you respond?

A test contains 12 problems. The teacher gives 24 points for each correctly solved problem and withdraws 15 points for incorrectly solved problems. If a problem is not solved it is considered incorrect. Ron claims he got a zero for the test. That is impossible says Mia. Is there any reason for mia to say that?
