Teaching Material:
� Required Text:
S. M. Ross, A First Course in Probability, 9th Edition (2014).
This introductory text has a very clear exposition, numerous exercises, and applications of probability theory
to everyday problems and situations.
� Recommended Texts:
W. Feller, An Introduction to Probability Theory and Its Applications. Third Edition, J. Wiley & Sons (1967).
R. Weber, Probability.
S. M. Ross, Introduction to Probability and Statistics for Engineers and Scientists, Fifth Edition (2014).
Prerequisites: Graduate students who have finished a basic course in calculus are allowed to take the course.
Grading: Midterm: 30%, Homework 20%, Final Exam: 50%.
Outline of the Course: This is a first course in probability that does not assume any previous knowledge of
probability. It will provide an introduction to advanced mathematical concepts and methods that find extensive use
in many fields of modern Data Science and Operations Research. The course will have a theoretical focus, but theory
will be motivated and illustrated with several examples from areas such as business and engineering. The course will
broadly follow Ross’s ‘A First Course in Probability’, with classes providing intuition and elaboration.
This course is a prerequisite for Stochastic Processes and for Stochastic Calculus for Finance.
Homework: Assignments, given on a weekly/biweekly basis, are to be done individually, unless otherwise stated.
You may discuss the problems with each other, but the work that you submit must be your own. You are expected to
refrain from using solutions from other sources (e.g. previous years’, classes, etc). If you do use outside information,
you must state your sources.
Participation: Classes will be a two-way process, and you will be expected to participate in class discussions and
activities. You may be asked to prepare presentations for classes. I will be available after class for questions, and
will respond to emails promptly.
Course Syllabus:
• Week 1: Introduction
• Week 2 (Ross, Chapter 1): Principles of combinatorial analysis. Examples of combinatorial problems. Permu-
