Introduction to Probability
(Second Revised Edition)
by Charles M. Grinstead and J. Laurie Snell
This book makes frequent references to programs that are available on the web. I'll be using the Maple
versions, but they are also available for Mathematica and TrueBASIC. You can find all of them at


There will be 1 midterm exams and a cumulative final exam.   You may not consult with
anyone but me on either part of an exam. You will not be able to use your book, notes or
calculator on the exams unless it explicitly says so on the exam . Tentative dates for the
midterm exams are as follows.
Midterm Exam 
Midterm Exam Solutions
Monday, October 22  Chapters 1, 3, 4, 5, 6
Final Exam Saturday, December 8
4:00 -- 6:00
Chapters 7, 8, 9, 11

The Registrar's Office schedules the final exam, which will occur during the period
December  6 --10. If you must make travel plans before the schedule for final exams appears,
do not make plans to leave Hanover before December 11.  Exams will not be given early to
accommodate travel plans.

Homework Policy

There will be homework assignments due each week.  There may also be a few
longer homework assignments, distributed periodically during the term, which
you will have one or two weeks to complete.  Homework will be graded out of
10 points, and you will receive an automtic five points for making an attempt at
all the problems.  Late homework is eligible only for the automatic 5 points.  If
you have a valid reason for turning in homework late (such as illness or a family
emergency) please talk to me.  Your lowest two homework grades will be dropped
before computing your end-of-term average.

You may (you are encouraged to) work  together on the homework assignments.
However, the work you turn in should be your own. This means that after whatever
discussions you have about the problems, you should write up your own solutions in
your own words. If you work with someone else from the class, please list their
names at the top of your assignment.


The midterm will count for 35%, the final will count for 40%, and the
homework will count for 25% of your final grade.

The Honor Principle

Every student who matriculates at Dartmouth agrees to abide by the academic
honor principle.  You have an obligation to act with integrity in your own
academic work, and to take action if you observe honor code violations by
others.  Academic integrity is essential to the scholarly enterprise and we take
it seriously.

In Math 20, you are encouraged to work together on homework problems,
and to use professors, other students, other textbooks, and generally any
resource you can find that will help you understand and work the problems.
You must write up the homework solutions by  yourself in your own words.
In brief, collaborate but don't copy.

You must do all work on exams independently, without giving or receiving
assistance of any kind.

Special Concerns

Please talk to me as soon as possible, or whenever something comes up, about
any special concerns you have about the class.  If you have a disability and may
require disability-related accommodations, talk to me as soon as possible; this
includes invisible disabilities like chronic diseases, learning disabilities, and
psychiatric disabilities.  If you have athletic or other extracurricular commitments
and hope to accommodate them (for example, by taking midterms at alternative
times), talk to me.  If you are ill and fall behind on work, talk to me.  If you are in
any way concerned about the course or your performance in it, talk to me.
If you can't do the homework, talk to me. Make an appointment, either after class,
by phone or via blitzmail, if you can't make regular office hours.
