Probability models Part A. Probability models Part B. Two hour exams, Wednesday, July 19 and Wednesday, August 9, in class.

A final exam covering all material of the course will be scheduled later. Homework assignments will be listed there shortly after each class period, plus additional key information such as sections to be covered on the hour exams shortly before each exam. You can also use this page to access Chance project home page.

From there you can access the on-line version of the Kemeny-Snell-Thompson textbook, as well as the Kemeny lectures on finite mathematics.

Assigned daily, due at the beginning of the next class period in the homework box outside Bradley marked Math 6 In; graded papers will be returned before the next class in the section marked Math 6 Return. Each assignment will be graded on a basis of 3 points for essentially all correct work, 2 points for work that is mostly complete but may have some errors, 1 point for work that is turned in but not very good.

No work will be graded that is more than one class period late, and only three late papers per student will be accepted for any reason. You may discuss the homework with one another. However, in each assignment turned in you must have done the majority of the actual mathematical work, and all of the write-up, independently.
