**Material covered:** Exam #1 will cover all material through and including Lecture 6 (random variables and expectation).
This includes everything on Problem Sets 1 and 2 and in Section Handouts 1 and 2.

**Logistics:** The CS109 Week 4 midterm is a two-hour, closed book, closed calculator/computer exam.
You are, however, allowed to bring **two** pages (front and back) of notes,
formatted in any way you like.

**Answer Format:** You are going to be solving probability questions by hand. To that extent
we are not interested in numeric answers, but rather in formulaic answers. It is fine for your
answers to include summations, products, factorials, exponentials, and combinations, unless the
question specifically asks for a numeric quantity or closed form. Where numeric answers are required,
the use of fractions is fine. You must show your work. Any explanation you provide of how you obtained
your answer can potentially allow us to give you partial credit for a problem.

**Practice material:** Previous iterations of this course have had a midterm that may have covered slightly different material
than you are responsible for. To help you practice the concepts for our Spring Quarter 2023 Mid-Quarter Exam #1, we have provided these
previous midterms in whole. Feel free to post on Ed to clarify whether a certain question from a practice exam covers material
that will be on this quiz.

**Material covered:** Quiz #2 will cover all material through Lecture 15's slide deck, Problem Set 4, and
Section Handout 5.

**Logistics:** The CS109 Week 7 midterm is also two-hour, closed book, closed calculator/computer exam.
You are, however, allowed to bring **two** pages (front and back) of notes,
formatted in any way you like.

you may be asked to write code or analyze code I give you. Any code you
write can be written in a pseudo-code version of Python, and we won't really
assign any points to syntax.
