Spring, 2011 David F. Anderson

Summary: Math 431
Spring, 2011
David F. Anderson
Exam 1 notes:
1. The exam is comprehensive and covers Chapters 1, 2, 3, and 4 (up through Section 4.5).
You must be able to:
(a) Know how to compute probabilities and expectations when they are handed to you,
i.e. be technically proficient. This is a minimum.
(b) You must be able to turn situations (i.e. word problems) into something you can
compute. This is the harder part, but is much more useful and comes from practice.
As I've said many times, the best course of action is to define random variables
("let..."), write down everything you know (think about assumptions (independence,
etc.) you are making), write down (in mathematics) what you need to solve for, and
only then try to solve the problem.
(c) You need to know how to do the types of proofs you have seen in class and have done
in the homework.
2. Study techniques: Review notes/text. Review all homework problems including my solu-
tions online. Choose more homework problems from the text. WORK TOGETHER and
have conversations about the material!
