# Probability & Statistics

## Homework 3: due February 14

In preparation for the midterm on February 16, you will create your own notes on discrete probability and the basic statistical method. Here are some requirements and guidelines:

• The main goal is for you to construct an organized understanding of probability in your own mind. How do each of the definitions fit together? Why did someone define things this way? In what order should things be defined? How do the concepts build upon each other?
• You should write it without looking at your notes: try writing as much of your outline of the course as you can, and only when you're completely stuck look at your notes from class. But even then, look at them, then put them away before resuming writing.
• Come up with examples of your own for each topic, definition, or concept. Try to use different examples than we have in class. And use multiple examples to show the full range of possibilities. For example: you should have an example of an event that is not an outcome, and an event that is an outcome, to show that both are possible.
• Be precise with any definitions you include. Precise definitions are used in mathematical proofs.
• Type if possible, and if not, write neatly. Staple the pages!
• You should turn in a copy of your notes, not the original since I will not return it in time for you to study it.
• It should be around 4 pages in length, depending on how big you write.
• Feel free to ask me any questions you might have
