Text: *A First Course in Probability * by Sheldon Ross, Prentice Hall,
Fifth Edition. The course will cover a substantial portion of the first
eight chapters.

Concerning grades: Grades will be based on three fifty
minute in-class exams (100 points each), a composite homework
grade (100 points) which is described further below, and the final exam
(200 points, thought of as two equal grades of 100 points). The worst of
these six scores will be weighted half, so that course grades will be based on
totals out of a possible 550 points.

The tests will be relatively straightforward, and I intend to
use absolute scores, not a curve. Thus, on a given exam, A+ is
98% or better, A is 93%, and A- is 90%, etc., so that, for
example, B+ is 88%, C- is 70% and D- is 60%.

If I feel that an exam was too hard I may lower these lines
slightly, but I will not change them if the exam was too easy.
Thus, a student with a total score of, say, 495 is guaranteed at
least an A- in the course.

Homework will be collected weekly. Late homework will not be accepted:
instead, a certain number of the worst grades (I will specify how many at
the end of the course), will not count, and these, for most people, will
include
all missed homework. E.g., if your ten best homework grades were the
ones counted and you averaged 80% on those homeworks but had zeroes
on all the rest, your homework grade would be 80 (out of 100).

The assignments will be initially from Ross. After a while, supplementary
problems will be assigned from a course pack. Your homework solutions
should show work or an explanation, not just an answer. (In many cases,
the answer is in the back of the book.)

Try the homework problems before they are due, so that you can ask about
the ones you don't understand in class. Usually, I will work a different but
similar problem.
