There are 100 exam points on this test representing 10 class points. This is your only document. You are disallowed from asking anyone else other than me for help, as well as share any files or other resources; on the other hand, I will be widely available by email for any questions you may have.
There are 3 Sections to this part of the examination:
Section 1 Short Answer 60 points
Section 2 Sets 20 points
Section 3 Probability 20 points
Before submitting, make sure to recheck your solutions/answers (e.g., are they properly displayed with units and the appropriate number of decimals?). Make sure that you are adhering to all of my course and examination requirements; once the due date/time has passed, you will have no opportunities to resubmit.
In some cases, you will have to build your own model. You may certainly reuse any models already available to you, whether on this examination, or in a previous HW or solution set.
