(f) A consistent set of formulas that contains both a contingency and a tautology. (g) An invalid argument with two premises where the premises and the conclusion are all contingencies. (The contingency requirement is just there to rule out some very silly answers.) P (h) Two formulas (call them "p" and "q") such that the argument q is valid. XAY Write your answer in the form: "p > and q = Page 2 (i) Two formulas (call them "p" and "q") where the set {p.q} is consistent, but the argument P is invalid. 9 Write your answer in the form: "p= (1) Bonus: A valid argument where the conclusion is a contradiction. and q=
