Math 335 – Probability (Fall 2007)

Instructor: Kevin Woods, King 220B, Kevin.Woods@oberlin.edu

Class: MWF 3:30-4:20pm, King 237.

Office Hours:
Monday 4:30-5:30pm, Tuesday 2:30-4pm, Wednesday 10:30am-12pm, Friday 12-1:30pm, and by appointment. Also, feel free to stop by any time my door is open (but be understanding if I say I am too busy).

Required Textbook:
Richard Durrett, The Essentials of Probability, Duxbury Press, 1st and only edition.  We will cover basically the whole of this fairly short book.

Other Recommended Books:
Ross, A First Course in Probability.  On reserve.
Grinstead and Snell, Introduction to Probability. Available FREE under GNU public document license at http://www.dartmouth.edu/~chance/teaching_aids/books_articles/probability_book/book.html.
Both of these books have lots of great examples.  Grinstead and Snell is a little more leisurely than Durrett or Ross, and it feels very “wordy” to me, if you like that sort of thing.

Blackboard:
Under “Quick Links” on college website. I will post homework, reading, other announcements, and grades on Blackboard.

Grading:
Problem Sets (35%),
Two Take-Home Midterms (20% each),
Final Exam (25%).

Problem Sets (35%).
The best way to learn the concepts in this course is to get your hands dirty!  I hope you will work in groups on these, though your written solutions must be in your own words.  This is also an opportunity to work on writing careful, clear proofs and explanations.  Good mathematics is articulate mathematics! Explain things carefully and in complete sentences. Imagine that another student in the class who hasn’t done this problem yet will read your solution: they should be able to understand it without having to ask you questions. These problems will be graded very strictly for how coherently written they are. Problem sets will be due approximately every Wednesday.  Your lowest problem set grade will be dropped.
Honor Code: You should (but aren’t required) to work together on these problems, but your written solutions must be your own. In particular, you should never look at another student’s write-up. Please indicate on your solutions who you worked with.  You may use outside sources, as long as they don’t directly address the assigned problem or a substantially similar one.  Please cite any sources you use that helped you.
Late Work Policy: If they are handed in before I leave my office that day (no guarantee when that is), you get full credit.  If they are handed in the next school day before I leave, you get 90%. Two school days, 70%, three school days 50%, more than that 0%.

Take-home midterms (20% each).
Tentatively due Wednesday, October 10 and Wednesday, November 21.  You will choose a continuous 24 hour period within the span of about 4 days in which to take the test.  The exams will be designed to be doable in 3 or 4 hours, but you’ll have the extra time to “sleep on it.”  You will work alone and be able to use the textbook and notes, but no other outside sources.
   
Final Exam (25%).
Thursday, December 20, 9-11pm. The final exam will cover the entire course.  It will be closed book, but you will be able to use something like an 8.5x11 sheet with notes.
