Probability, Jim Pitman. Students can view and download the text online at SpringerLink (campus network access required). An affordable paperback copy may also be purchased through this link.


Emails, zoom link and office hours of the GSIs available on the Staff page.


Mastery of the material in Appendices 1-4 of the text, fluency with calculus (derivatives and integrals) in two variables, and – these are crucial – clear logical reasoning and strong problem-solving skills. Test yourself on some practice problems.

Class Website:

The primary class website is This will contain lecture notes and video links. B-courses is a secondary website for the class. I will post pre-lecture notes on b-courses/pages for you to download before class.


There will be a student run Piazza site for this class. The top 10 student answerers (i.e. students who respond to other student’s questions) will get up to 1% extra credit added to their final grade total in bCourses after the curve.

  • Assignments are posted on the Homework tab here. They are due by 11:59 pm on the day due (noted below) on Gradescope.

  • Papers will be graded on a 0/1 scale. Each assignment will consist of 8 problems. A good attempt at 6 or more problems will receive the score of 1; anything else will get 0. Course staff will define what constitutes a "good attempt." We will be looking for reasoning and detailed work shown –it is assumed that you will show work or provide reasoning whether or not the question asks for it.

  • Your two lowest homework scores will be dropped from the computation of the homework component of your final grade.

  • No late homeworks will be accepted and cheating will not be tolerated. While you are encouraged to work with other people, you must write up your own solutions.

  • There will be three long quizzes during the term, during section time, on dates listed in the calendar below. There will be a convenient time for international students. You DO NOT have to take your quiz in the section in which you are enrolled. Students with DSP accommodationsmust contact Prof. Lucas to make arrangements as necessary.

  • Q1: Wednesday, February 3
    Q2: Wednesday, February 17
    Q3: Wednesday, March 31

  • Your lowest quiz score will be dropped from the computation of the quiz component of your final grade.

  • Midterm 1: Friday March 5, during class time.

  • Midterm 2: Friday April 23, take home midterm (details TBA).

  • Final: Tuesday May 11, 7-10pm.

  • The final will clobber the first midterm but not the second midterm.

  • The max of:

  • 10% Homework, 20% Quizzes, 20% Midterm 1, 5% take home Midterm 2, 45% Final

  • 10% Homework, 20% Quizzes, 5% take home Midterm 2, 65% Final

  • If you don’t take the final exam you will not pass the class.

    Your two lowest homework and your lowest quiz score will be dropped.

Academic Honesty

Being an online class academic honesty is of particular concern. I will do everything I can to remove incentives for you to feel like you need to cheat. I am making two midterms so that there is more chances for you to demonstrate what you know. Second, the exams will be designed to be difficult to cheat on. Third, please know that I take the Berkeley honor code very seriously and have years of experience catching cheaters. Fourth, if we suspect someone of cheating, we reserve the right to give the student an oral quiz or exam and test if the student understands what they wrote.

Please familiarize yourself with UCBs Academic Honesty Policy (see the Center for Student Conduct website: ). I encourage you to discuss homework problems with other students and to work together, but copying is never appropriate. (You should never write down anything you don't understand!) I strongly encourage you to familiarize yourself with the definition of plagiarism, and to avoid engaging in it. Violations of the UCB’s Academic Honesty Policy, including instances of plagiarism, will be reported to the University and an appropriate penalty will be implemented. (This may range from a failing grade on an assignment to an “F” for the course, in addition to writing letters of reflection and apology to UCB’s administration.)
