**Note on conflicts:**
At the time the exam time and date was voted on, only one
person had indicated a legitimate academic conflict. Legitimate conflicts
may be lab sessions, scheduled classes, non-personal trips. In case the
conflict is with another evening exam held at the same (or an overlapping)
time period, University guidelines on prioritizing of conflicts apply:
According to these guidelines, the larger of the two classes is
responsible for arranging a conflict. If you believe you have a
legitimate conflict that cannot be resolved in other ways, email me
(ajh@uiuc.edu) with details (e.g., details on the conflicting class/event,
and exact start and end times), as soon as possible, but no later than
**Friday, March 13.**

**Location:**
The exam will in the same room as the first midterm,
**Room 1404 Siebel Center,**
Here are links to maps:

- Map of Siebel Center. Siebel is located at the corner of Stoughton and Goodwin Ave.
- Floor plan for Siebel Center.

**Exam Rules:**
**No books, notes, formula sheets, etc., and no calculators.**
The problems will be such that no calculator is needed;
you can, and should, leave all answers in "raw" form, just as in the
hw problems.

**Exam content:**
The exam will cover Chapters 3 and 4 of the text, corresponding to the class
material covered through Wednesday, March 11, and homework assignments
through HW 6. (I will hand out solutions to HW 6 on Monday.)
See below for a detailed syllabus.

The exam will have 4 - 6 problems, generally with several parts. Most of the problems will be comparable in difficulty to the homework problems, the examples from class and from the book. The problems are expected to be done in the same way as the hw problems; in particular: solutions (with explanations) rather than mere answers are expected; the final answers can and should be left in "raw" form; and the problems should be solved using the methods developed in class.

The exam may include one or two conceptual questions, e.g., questions asking to state a formula, definition, property, or theorem. (Those types of questions wouldn't make sense as hw problems or examples, since the answers can be found in the text.)

**Sample exams:**
Below are links to Math 461 exams given in the past few years.
These should give you an idea of what to expect, in terms of the difficulty
and nature of the problems. Keep in mind, though, that there may be some
differences in coverage of the material.

**Chapter 3: Conditional probability and independence**- Conditional probability (3.2, 3.5)
- Bayes' Rule and Average Rule; (see Handout for formulas) (3.3; you can skip Ex. 3e - 3h and the material on odds ratios on p. 79-80)
- Independence (3.4)

**Chapter 4: Random variables**- Definition and examples (4.1)
- Discrete distributions, general theory: p.m.f., c.d.f., expectation, variance (see Handout for formulas) (4.2--4.5, 4.9)
- Discrete distributions, special distributions: Binomial (4.6 through p. 157), Poisson (4.7 through p. 163), geometric (4.8.1), negative binomial (4.8.2), hypergeometric (4.8.3) (see Handout for formulas).
