Decide whether the argument is valid or a fallacy, and give the form that applies. I'll win the contest, or you will. You won't win the contest. I'll win the contest. Let p be the statement "I'll win the contest," and q be the statement "you'll win the contest." The argument is by [(p→q) ^ (q→ r)] → (p → r), [(pq) q] →→ p. [(p v q) q] → p, [(pq) ~q] → ~P, [(p →q) ^ -p] →→ ~q, or [(pq) Ap] →→q,
