2. Let p, 9.r be propositions. Based on given truth values of individual propositions or compound propositions decide the missing truth value(s), if possible. Pick the correct answer (circle or underline, or use a color). No explanation is necessary. a) If p ET Aq=F Ar=T then (p + -9) 9 (par) = ... TRUTH FALSE cannot be decided b) If p ET Aq=Far F then (p 9) (qr) = .... TRUTH FALSE cannot be decided c) If (p1-9) (p +r) = F, then par... TRUTH FALSE cannot be decided 3. Prove that if n is an integer leaving remainder 1 after division by 4, then n. Provide the type of your proof and all details
