The course is designed to provide the basics in Discrete Mathematics. Part I of the text lays the basis for doing mathematics in logic, sets, and numbers. Part II then proceeds with combinatorics. Finally, we deal with probability (from the supplementary text).
Reading and understanding of the text in the respective section goes each time WITHOUT SAYING as part of the HW. HW problems will be assigned daily. Each quiz is based on the previously assigned HW and/or corresponding section(s) of the text.
Here is a PRELIMINARY list of HW assignments (it can be modified as we proceed):
Probability Book.
Ch.3: Introduction to probability 45,47,58.
Ch.4: Conditional probability and independence 54-57,61,62,65,66,73,75,78,83,85.
Ch.5: Random variables 56,58,62,63,66.
Grading Policy: The course is broken into 9 units as follows: Final (R, 5/8, 9am-11am) is 4 units, Midterm (R, 3/6) is 2 units, Quizzes (on Tuesdays, starting week 4) 2, Attendance 1. The lowest of the above units will be dropped. The average of the remaining 8 units determines your grade for the course.
Texts: Discrete Mathematics by Biggs, 2nd edition; and Theory and Problems of PROBABILITY by Lipschutz and Lipson, 2nd edition
