Math 4810/5310 Probability FALL 2014 Department of Mathematical and Statistical Sciences University of Colorado Denver Instructor: Burt Simon Office: AB 4209 Office Hours: TR 3:00-4:00, or by appointment Phone: 303 315 1710 Website: www.math.ucdenver.edu/~bsimon Email: burt.simon@ucdenver.edu Course dates/times: TR 12:30-1:45 Course location: NC 1314 Text: Fundamentals of Probability with Stochastic Processes, 3rd ed. by Saeed Ghahramani Welcome! Probability is a fascinating and very useful mathematical theory. Math 4810/5310 is a standard introduction to probability theory. By successfully completing this course you will be ready to take courses in mathematical statistics, probabilistic modeling, stochastic processes, financial engineering, actuarial science, and various engineering fields. Please check the class web page regularly, which can be linked to from my page at math.ucdenver.edu/~bsimon. The class web page will have the weekly assignments, announcements, exam solutions, etc. I encourage students to participate in class by asking questions and answering (rhetorical) questions that I ask during class. University Course Catalog Description: Examines elementary theory of probability, including independence, conditional probability, and Bayes’ theorem; random variables, expectations and probability distributions; joint and conditional distributions; functions of random variables; limit theorems, including the central limit theorem. Note: No co-credit with MATH 3800. Prereq: MATH 3191; Coreq: MATH 2421. Cross-listed with MATH 5310. Semester Hours: 3 to 3 Course Overview: Introductory probability courses like this one cover axioms of probability, combinatorial probability, conditional probability, random variables (discrete, continuous, and multivariate), Expected value (mean, moments, variance, covariance, etc.), and some limit theorems (laws of large numbers, Central Limit Theorem). Course Goals and Learning Objectives: A. Overall Learning Objectives: By successfully completing this course, students will be familiar with all the basic concepts of probability theory listed in the Course Overview, and will understand how they tie together. Students will be able to calculate probabilities, expected values, etc., and be able to formulate probabilistic solutions for simple applied problems. B. Learning Outcomes: Problem Solving: Students will learn to solve problems involving uncertainty that are posed as generic probability calculations, and as real-world applications of probability theory. Creative Thinking: Students will learn to distill a probability problem from a description where it may not be obvious how probability theory applies Critical Thinking: It is easy to misapply probability theory, so students will learn to apply the theory correctly. C. Major Topics: axioms of probability, combinatorial probability, conditional probability, random variables (discrete, continuous, and multivariate), Expected value (mean, moments, variance, covariance, etc.), and some limit theorems (laws of large numbers, Central Limit Theorem). D. Rationale: Probability is required as a prerequisite for many upper division math courses, like statistics, probabilistic modeling, stochastic processes; and is useful in business, engineering, and other technical fields. Course Prerequisites: Math 3191 (linear algebra) Course Credits: 3 credit hours Required Texts and Materials: Fundamentals of Probability with Stochastic Processes, third edition, by Saeed Ghahramani Course Schedule: The following schedule of course materials covered is tentative, but the dates of the exams will not change.

Typically the assignment will be posted on the class web page on Tuesday, and will be due the following Tuesday. You are expected to turn in every homework assignment on time, since the purpose of the homework each week is to practice the material covered in class that week. Furthermore, homework sets will be discussed in class the day they are due, so late assignments will not receive full credit. Homework sets are expected to be written up neatly so they are easy to read (preferably using Word or Latex). Working collectively on the homework assignments is encouraged! There is no penalty, but please list the people you worked with on the papers you turn in. Basis for Final Grade: Your final grade will be based on your exam scores (two midterm exams and a final exam), weekly homework sets, and intangibles such as class participation. The intangibles can only increase your grade. Exam and homework grades will start out as numerical (e.g., between 0% and 100%), but will be “curved” and translated into letter grades, “A+” at the top and “F” at the bottom. These letter grades are associated with the same numerical values that your GPA is based on, i.e., A+ = 4.3, A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, and F = 0.0. In the absence of “intangibles”, your final grade will be a weighted average of the letter grades on your exams and homeworks. You will get a simple homework grade, which will be the average of the individual scores, with the lowest score deleted. The weightings will be as follows: Homework (20%), Midterm Exam #1 (25%), Midterm Exam #2 (25%), Final Exam (30%). Grade Dissemination: I will try to grade homework sets within a week of when they are due, and exams by the next class after they are taken. They will be returned in class with grades on them. If you sense a mistake in my grading, please send me an email, or come to my office hours to discuss. Course Policies A. Attendance: I will not take attendance, but students are expected to attend every class. You will be responsible for material I cover in class, whether or not it is in the textbook. Class participation is one of the important “intangibles” that can impact your grade. B. Late Work Policy: Normally I will not accept late homework sets, and I will not make arrangements if you miss an exam. Under unusual circumstances arrangements can be made. Try to give me as much lead time as possible if you know something will force you to be late with an assignment, or miss an exam. C. Extra Credit Policy: There is no “extra credit” in general, but students can try to raise their grades by being attentive (and participating constructively) in class, and demonstrating competence in my office hours. D. Grades of “Incomplete”: I will follow university procedures on “incompletes”, i.e., they are only given in situations where unexpected emergencies prevent students from completing the course and the remaining work can be easily finished the following semester. Incomplete work must be finished the next semester or the grade automatically turns into an F. E. Group Work Policy: Students are encouraged to collaborate on homework sets, as long as they acknowledge their collaborators. There is no penalty for working together. Of course, no collaboration is allowed on exams, as that is considered cheating. F. Announcements: I will use the class web page for all communication that is meant for the whole class. Please check the page regularly. Private communication is best done by email. I will typically respond within a day. G. Laptops, Cell Phones, etc.: You are free to use your devices as you see fit during class. (No phone calls or texting, of course.) The rules during exams will be announced prior to the tests. Usually my exams are open-book, open-notes, but electronic devices (calculators, computers, etc.) are not allowed. H. Civility: Students are expected to be quiet and attentive during class, although raising your hand to ask a question or make a comment is welcome and encouraged. Dishonesty: Students are expected to understand intuitively what proper ethical conduct means in the context of a college mathematics course. If you are caught cheating you could fail the class or (at least) have your grade lowered, so don’t even try it. Fall 2014 CLAS Academic Procedures and Deadlines The following policies, procedures and deadlines pertain to all degree-seeking students in the College of Liberal Arts and Sciences (CLAS). Please also consult the Official University Academic Calendar and see you advisor if you have questions or concerns. Schedule verification: It is each student’s responsibility to verify online that his/her official registration and schedule of classes is correct before classes begin and prior to the drop/add deadline. Failure to verify schedule accuracy is not sufficient reason to justify a late adds or drops. E-mail: Students must activate and regularly check their official CU Denver e-mail account for university related messages. Those who forward email should check CU Denver e-mail regularly for messages not automatically forwarded. Waitlists: Students are automatically notified if they are enrolled in a class from a waitlist via their official CU Denver email account. Students are not automatically dropped from a class if they never attended, stopped attending, or do not make tuition payments, though instructors may request administrative drops. Waitlists are purged after the 1st week of classes. To add a course from August 26September 3, it is the student's responsibility to get a CLAS Instructor Permission to Enroll in a Course form at http://www.ucdenver.edu/academics/colleges/CLAS/clas- advising/Pages/CLASAdvising.aspx or http://www.ucdenver.edu/academics/colleges/Graduate-School/Pages/default.aspx, have it signed electronically or in person and submit it according to the instructions on the form. Students and faculty will receive emails with directions for completing registration via official university email and students must complete registration and verify their schedules before census, September 3rd, by 5p.m. After Sept 3: students should meet with their CLAS advisor to learn more about how to petition to add a course late. Late adds (after September 3, 2014) will be approved only when circumstances surrounding the late add are beyond the student’s control. This will require a written petition and verifiable documentation. Petition forms are available in the CLAS advising office, NC 4002, or the Graduate School, LSC 1251. The signature of a faculty member on a Schedule Adjustment Form does not guarantee that a late add petition will be approved. Late drops (after November 10, 2014) will be approved only when circumstances surrounding the late drop are beyond the student’s control. This will require a written petition and verifiable documentation. Petition forms are available in the CLAS advising office NC 4002 or the graduate school, LSC 1251. The signature of a faculty member on a Schedule Adjustment Form does not guarantee that a late drop petition will be approved. Tuition: Students are responsible for completing arrangements with financial aid, family, scholarships, etc. (depending on tuition plan selected) to pay their tuition prior to Census Date, September 3, 2014. Students who drop after that date are (1) financially responsible for tuition and fees, (2) academically responsible and will receive a "W" grade, and (3) are ineligible for a refund of COF hours or tuition. Graduation: Undergraduate students wishing to graduate in Fall 2014 should (1) first meet with their CLAS advisor; (2) meet with their major and minor advisor(s), who will complete the electronic form required to verify eligibility to graduate; and (3) apply for graduation online through UCDAccess. These steps must be completed by no later than 5PM on September 3rd, which is an absolute deadline without exception. Graduate students wishing to graduate in Fall 2014 must apply for graduation online through UCDAccess and have a Request for Admissions to Candidacy on file with the CU Denver Graduate School (LSC 1251) no later than 5 PM, September 3, 2014, which is an absolute deadline without exception. Important Dates and Deadlines All dates and deadlines are in Mountain Standard Time (MST). August 18, 2014: First day of classes.
