| HomeMath 493, Fall 2010
Thursday, December 23The Math 494 webpage is now up (in a preliminary version). This webpage will shortly be moved to an archive address of http://www.math.wustl.edu/~russw/f10.math493/ -- it will also continue to be linked from the Teaching section of my homepage, and from the department list of syllabi webpages. Thursday, December 23 The final exam is graded, and scores are posted on Telesis. I regard a score in the 30s as an A, and a score in the 20s as a B. Thursday, December 16The last homework is graded, and can be picked up during my office hours on Friday or Monday. Monday, December 13I've now posted a high-level topics list for the new topics covered by the final. Friday, December 10 Suggested study problems are posted in the homework section. Wednesday, December 8Don't forget to fill out evaluations! Tuesday, December 7Now posted is a proof of the Chevyshev inequality for continuous random variables. Wednesday, November 24 Happy Thanksgiving! I've posted grades in Telesis. Monday, November 15Also, if anyone picked up an extra copy of the textbook on Friday, please bring it to me. Monday, November 15 Exam 2 is posted online. Note that there were two variants of the exams, which differed only in the ordering of the T/F questions. Tuesday, November 9The topics from Chapter 3.3 that will appear on the exam are restricted to the single 2-shuffle model, and variation distance. Specifically, I'm taking multiple shuffles and the proof that "7 shuffles suffices" off the table. Sunday, November 7 To help you study, I've posted a high-level list of some of the main topics that will be covered on Exam 2 this Friday. Saturday, November 6On problem 38, you can assume that X_{1} and X_{2} are continuous random variables. (How would the proof for discrete random variables work?) Tuesday, October 26 In problem 32, the set of events corresponding to each edge in the graph being "open" should be taken to be mutually independent. Monday, October 18Note that "rising" sequence in p131 #1 refers to what we called in class a "rising-by-1" sequence. (I like my terminology better -- "rising" sounds like the opposite of fall, which is not actually so.) Wednesday, October 6Exam 1 is posted online. Note that there were two variants of the exams, which differed only in the ordering of the T/F questions. Sunday, October 3 To help you study, I've posted a high-level list of some of the main topics that will be covered on Exam 1 this Wednesday. Tuesday, September 28Problem 11 is vague as to whether one should find the probability that a fixed candidate gets the job or that some candidate gets the job. Either interpretation is fine, as long as your writeup makes it clear which you are using. Wednesday, September 22Homework 1 was returned today. A selection of 4 problems were graded, each out of 5 points, so that the entire homework is out of 20 points. Wednesday, September 15 A runnable version of the simulation from Homework 1 is available here. Monday, September 13I've set my office hours for Tuesday 1 - 3 pm. After class is often also a good time to grab me, if you have a few quick questions. Saturday, September 11The Java programs that we've been running in class are linked from the links page. If you're puzzling over the simulation problem on the homework, then their source is similar, and looking at it may be somewhat helpful. Wednesday, September 8 The first homework is posted in the homework section. Friday, September 3 We noticed on Wednesday that in 30 coin flips, we often get 5 flips in a row which are the same (all heads or all tails). Saturday, August 21Welcome to Math 493!
