Please talk to each other about the homework, but under no circumstances copy from another's paper.  Odd-numbered exercises have answers in the back of the book.  Homework assignments early in the quarter will have both odd and even-numbered exercises, but the odds will be eventually eliminated.


Grading:  Your homework will be worth 100 points (10 points each), 

the three midterms 100 points each, and the final exam 200 points.  Total: 600 points.


First homework, due Fri, Jan. 6:

Chapter 1, #2, 4-14.  (Be sure you understand all of sections 1.1 and 1.2 before attempting the first homework set.)


Notes on the exercises.

#9: Be sure to tally the last place votes for all four candidates.  What is literally wrong with the way the tie-breaking criterion is worded? (Just imagine a computer programmer taking the criterion literally!)   How would you word a corrected version?

#10:  Notice that the tie-breaking criterion is better worded in this exercise.

#11, 12:  Would insincere voters always know ahead of time how to cast their ballots?  Would it make any difference whether a straw poll were taken before the actual vote?

#13:  You can always proceed by trial and error.
