Where and When
The course will takes in room B42 of the IFW building (consult map). During the five weeks of October 22 through November 25, the course will be held Mondays and Tuesdays, 9am till 6pm.
Schedule
For a rough schedule, we start 9:15 in the morning with two to three hours of lectures. After lunch exercises are worked out. The day is concluded by a discussion of material and exercises, 5-6pm on Mondays, and 4-5pm on Tuesdays.
Reading Assignments
Basic Examples of Probabilistic Analysis, Part I and Part II.
