Question

Q1 Show that the argument form with
premises (p A t) →(r V s), q → (u ^ t), u
→p, and ¬s and conclusion q→r is
valid by using rules of inference from
Table 1.
Q2 For each of these arguments, explain
which rules of inference are used for
each step.
a) "Linda, a student in this class, owns a
red convertible. Everyone who owns a
red convertible has gotten at least one
speeding ticket. Therefore, someone in
this class has gotten a speeding ticket."
b) "Each of five roommates, Melissa,
Aaron, Ralph,Veneesha, and Keeshawn,
has taken a course in
discrete mathematics. Every student
who has taken a course in discrete
mathematics can take a course in
algorithms. Therefore, all five
roommates can take a course in
algorithms next year."
c) "All movies produced by John Sayles
are wonderful. John Sayles produced a
movie about coal miners. Therefore,
there is a wonderful movie about coal
miners."
d) "There is someone in this class who
has been to France. Everyone who goes

6. Use a truth table to determine whether the following argument form is valid. Indicate which columns represent the premises and which represent the conclusion, and include a sentence explaining how the truth table supports your answer. Your explanation should show that you understand what is means for a form of argument to be valid or invalid. Argument form: P→ r q→ r ..pvqr
Truth Tables and Circuits Construct a compound statement using all of the logical connectives (~, v, ^, -->) at least twice. Your statement must have no fewer than 7 distinct statements, call them: A,B,C,D,E,F,G. Use a spreadsheet program to expedite constructions of the 128-row truth table. Once you've finished that, try coaxing your compound statement into a Tautology or a Contradiction.

Consider the following argument: “Companies use free samples to encourage sales, I help them.” Perform your own analysis of the argument using the concept of negative/positive rights.
Directions: For each proof, you must include (i.e., write) the premises in that proof. I do not want to see any proofs without premises. YOU CANNOT USE CONDITIONAL PROOF (CP), INDIRECT PROOF (IP), and ASSUMED PREMISES (A). Additionally, use only the 18 rules of inference found in the text and in the notes. You will lose points if you use any of the inference rules Resolution, Contradiction, Transposition, Idempotence and Identity.
