Abstract 
Basic concepts of probability are introduced in terms of finite probability spaces. The basic theory is often introduced in terms of simple models such as coin tossing, random walks, and casino games.

Grading 
Homework 20%, two mid term exams each 20%, final exam 40%. As much as possible, grades will be based on demonstrated knowledge. However relative performance may be used as a criterion for increasing grades, and grade borderlines will be chosen to place a relatively small number of students on borderlines. At the end of the term, the lowest of your 4 grades (hw, midterms, final) will be dropped, except if your final exam is your lowest grade, in which case the weight of the final exam will be halved. (So, if one of the midterms or hw is dropped, then the remaining 3 grades have weights 25, 25, 50; while if the final is the lowest, the four grades have equal weight 25, 25, 25, 25.) 
Homework 
Homework is due at the start of the class period on the due date. Late homework is generally not accepted unless there is a prior arrangement.

Exams 
The two midterm exams will be held in the evenings of April 19 and May 17 from 7:00pm to 9:00pm. These exams will be constructed so as to be doable in 60 minutes; the extra hour is to help you relax and not feel so rushed. The final exam will be held on June 3 from 8:00am to 11:00am. 
Honor Code 
Students are encouraged to work together to do homework problems. What is important is a student's eventual understanding of homework problems, and not how that is achieved. The honor principle applies to homework in the following way. What a student turns in as a homework solution is to be his or her own understanding of how to do the problem. Students must state what sources they have consulted, with whom they have collaborated, and from whom they have received help. Students are discouraged from using solutions to problems that may be posted on the web for previous offerings of the course, and as just stated, must reference them if they use them. The solutions you submit must be written by you alone. Any copying (electronic or otherwise) of anotehr person's code or solutions, in whole or in part, is a violation of the Honor Code. The honor principle applies to exams as follows: Students may not give or receive assistance of any kind on an exam from any person except the professor or someone explicitly designated by the professor to answer questions about the exam. Students may not use a computer during an exam, but they may use a calculator to help with simple arithmetic. If you have any questions as to whether some action would be acceptable under the Academic Honor Code, please speak to me, and I will be glad to help clarify things. It is always easier to ask beforehand. 
Disabilities 
I encourage any students with disabilities, including "invisible" disabilities such as chronic diseases and learning disabilities, to discuss appropriate accommodations with me, which might help you with this class, either after class or during office hours. Dartmouth College has an active program to help students with disabilities, and I am happy to do whatever I can to help out, as appropriate. The Student Disabilities Coordinator, Nancy Pompian, can be reached at 62014 if you have any questions. Any student with a documented disability requiring academic adjustments or accommodations is requested to speak with me by the end of the second week of the term. All discussions will remain confidential, although the Academic Skills Center may be consulted to verify the documentation of the disability and advise on an appropriate response to the need. It is important, however, that you talk to me soon, so that I can make whatever arrangements might be needed in a timely fashion.
