Math 151 - Introduction to Probability Theory

Winter 2003

Older Announcements:

2/9: Extra office hours Monday 2/10: 3pm-5pm.

2/9: Although I am writing the exam for 1 hour 15 minutes, I'd like to give 1 hour 30 minutes.
You may either start the exam at 1:00 and stay until 2:30, or start the exam at 1:15 and stay until 2:45.
If you start at 1:00, please choose a seat in the back part of the room.

If anyone has problems with both options, please email me.

2/6: Here are some practice problems for the midterm. All from Durrett:
1.3.22, 1.4.10, 1.7.16, 2.2.10, 2.3.12, 2.4.12, 3.1.12, 3.9.4
I'd expect you to be able to do 1.3.22 two ways: counting,
or conditioning on whether or not Jones is at an end seat.
The answer to 2.3.12 is 0.6, not what it says in the back of Durrett.

2/6: Durrett's typos.

2/4: Justify your answers on homework and exam problems, unless the problem specifically instructs otherwise.
"Justification" = your logic should be clear.
(This does not necessarily require writing complete sentences or even any words at all.)
My posted solution sets give a level of justification that is sufficient for full credit.

1/23: The homework assignment due each week depends only on material covered the PREVIOUS week in class.

For example, we first covered Bayes' Theorem in THIS week's classes.
So the homework due _this_ week does not require it.
But it is fair game for the homework due _next_ week.

There may be exceptions, if in some week we cover in class less than I had planned.
But I will always announce these exceptions.

1/15: In response to some questions:

Homework 1 depends only on what we covered the first week of class. In particular, you do not need the concept of independence.

1/7: More about Math 151 vs. Stat 116

1. If some course you plan to take in the future lists Stat 116
as a prerequisite, then taking Math 151 instead of Stat 116
does provide the necessary preparation (or more).

Also, if some degree requirement lists Stat 116, then Math 151
ought to be listed as a substitute, in my opinion. But you
should verify that this is the case.

2. As I indicated, in selecting examples, I will not be
specifically trying to avoid examples that may also have
been used in Stat 116. I'll simply choose what I think
that you and I will find informative and interesting
(e.g. paradox of wild-card poker).

But what I find interesting/informative for Math 151
will of course differ, in certain ways, from what other
instructors find appropriate for Stat 116 or MSE 120.
