CS109 Final
Sat, Aug 17th, 3:30 - 6:30 pm

Logistics

The CS109 final is a 3-hour, closed book, closed calculator/computer exam. You are, however, allowed to bring 10 pages (front and back) of notes in the exam, formatted in any way you like; these notes can include your notes from the midterm. Make sure to practice before the exam.

Location and Time

When: 3:30 - 6:30 pm Sat, Aug 17th
Where: room 300 of building 300

Coverage

The final will be comprehensive of all the material in the course through the last lecture. It will place special emphasis on the content covered on the psets, and will have more material from concepts that were not already covered on the midterm.

Answer Format

Just as on the midterm, 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. For example, describe the distributions and parameter values you used, where appropriate.

What about the phi function? You can just leave your answer in terms of phi (the CDF of the standard normal). For example $\Phi(\frac{3}{4})$ is a fine final answer. This was not the case in the past, so you will see questions which ask for a numeric answer in the practice exams.
