## Math 20

### Discrete Probability

Homework

Homework will be assigned for most class periods and will be due the following class period. Both homework assignments and solutions will be posted to the webpage. Please take the time to write up your solutions neatly and carefully! Late homework will not be accepted but your lowest three homework scores will be dropped.

You must cite other books or online sources if you use them to help solve a problem. If you enjoy working in groups, I encourage you to work with others in the class to solve the homework problems, but all homework is to be written up independently.
