CS70 Discrete Mathematics and Probability, Spring 2012 Homework 1 Out: Jan. 19; Due: Jan. 26 Instructions: Start each problem on a new sheet. Write your name, section number and “CS70” on every sheet. If you use more than one sheet for a single problem, staple them together (but do not staple different problems together). Put your solutions in the homework boxes on Soda level 2 by 5pm on Thursday, as follows: your solution to Q1 goes in box CS70–1, your solution to Q2 goes in box CS70–2, and so on. (Thus you will be putting your solutions in ﬁve separate boxes.) You are encouraged to form small groups (two to four people) to work through the homework, but you must write up all your solutions on your own. 1. [ Classical logic] Here is an extract from Lewis Carroll’s treatise Symbolic Logic of 1896: (I) No one, who is going to a party, ever fails to brush his or her hair. (II) No one looks fascinating, if he or she is untidy. (III) Opium-eaters have no self-command. (IV) Everyone who has brushed his or her hair looks fascinating.
