**Text (required):** Sheldon Ross,
*A First Course in Probability*, 7th edition, Prentice-Hall, 2006.

Where can I buy this textbook?

**Prerequisites:** Math 215 or 285 (Multi-variable calculus).

**From departmental course description:**

This course introduces students to the theory of probability and to a
number of applications.
Topics include the basic results and methods of both discrete and continuous
probability theory: conditional probability,
independent events, random variables, jointly
distributed random variables, expectations,
variances, covariances.
The material corresponds to
most of Chapters 1-7 and part of 8 of Ross.

**Grade** will be based on two 1-hour midterm exams, 25% each;
20% homework; 30% final exam (comprehensive).

Your lowest homework set score will be dropped.

This course will **not** be graded on a curve, i.e., there are not a set
number of each grade to be given out.
Every student with the total score of 90% (resp., 80%, 70%, 60%)
is guaranteed the final grade of A (resp., B or higher, C or higher, D
or higher).

There will be 10 problem sets.
*No late homework* will be accepted.
In each homework assignment, 5 problems will be graded.
All answers should be justified by a sound argument.
An answer lacking justification will receive no credit.
Collaboration on the homework is fine, but each person is responsible
for writing up her/his own solutions.
Due dates shown below are tentative;
actual due dates will be announced in class.
