Math 461: Probability Theory (Spring 2023)
An introduction to the mathematical treatment of random phenomena occurring in the natural, physical, and social sciences. Axioms of mathematical probability, combinatorial analysis, random variables and probability distributions, expectation, binomial distribution, Poisson and normal approximation, generating functions and the Central Limit Theorem. We will cover most of the material in the first eight chapters of the textbook.

| Textbook | Sheldon Ross, A First Course in Probability, 9th Edition, ISBN: 9780321794772. It is okay to use a different edition for studying. The books Introduction to Probability Theory by Hoel, Port and Stone; and Probability and Statistics by Morris DeGroot and Mark Schervish are optional as reference texts. The book Introduction to Probability by C. M. Grinstead and J. L. Snell is available free online. You can also freely view the ebook Introduction to Probability by Blitzstein & Hwang. | ||||||||||||||||||
| Prerequisite | Math 241 or the equivalent. We will use important topics from calculus, such as infinite series with positive terms (most calculations involve the geometric series and series derived from it), improper integrals and double integrals (change of variables formula, manipulating Gaussian integrals). | ||||||||||||||||||

| Grading Policy |
Homework: 20% of the course grade. Homework will be assigned weekly on Thursdays on Canvas, to be submitted at the start of next Thursday lecture or earlier in Canvas. Solving a lot of problems is an extremely important part of learning probability. You are encouraged to work together on the homework, but I ask that you write up your own solutions and turn them in separately. Late homework will not be graded. If for some reason you've done a homework but can't turn it in online, send it via email before class. Because of this strict policy on late homework, I will drop your lowest score. Please talk to the instructor in cases of emergency. Quiz: 15% will depend on weekly quizzes on Prairielearn. Problems will be based on that week’s homework material. I will drop your lowest quiz score. Midterm: 30%=2 x 15% will depend on two in-class midterm exams on (tentatively) Tuesday, Feb 28, 2023 and Tuesday, April 4, 2023. Each exam will be technically comprehensive, but emphasizing recent material up to the most recent graded and returned homework assignment. Exam problems will be similar to homework problems. Final: 35% will depend on a final exam on (tentatively) TBA. It will cover the most important topics of the whole course, emphasizing recent material somewhat. | ||||||||||||||||||
| Exam Policy | Make-up exams will be given only for medical or other serious reasons. If you discover that you cannot be at an exam, please let me know as soon as possible, so that we can make other arrangements. You must work completely on your own during exams (and any quizzes). I make my exams fair and similar to homework, so as long as you use the resources provided, you should do fine. If you have difficulties of any kind or fall behind in the course, please come talk to me as soon as possible. | ||||||||||||||||||
