16. Consider the following propositions: r = “ODD(N) = T," m = "the output goes to the monitor," and p = "the output goes to the printer." Translate the following, as in Exercise 15. (a) The output goes to the monitor if ODD(N) = T. (b) The output goes to the printer whenever ODD(N) = T is not true. (c) ODD(N) = T only if the output goes to the monitor. (d) The output goes to the monitor if the output goes to the printer. (e) ODD(N) = T or the output goes to the monitor if the output goes to the printer.

Hello. Please answer the attached Discrete Mathematics question correctly and follow all directions. *If you answer correctly I will provide a thumbs up for you. Thank you.
Use an indirect proof to show that each conclusion follows logically from the premises: P V Q R → -P 1. Premises: -(Q V S) Conclusion: ... -R Show that the hypothesis "it is not sunny this afternoon and it is colder than yesterday", "we will go swimming only if it is sunny", "if we do not go swimming, then we will take a canoe trip", and "if we take a canoe trip then we will be home by sunset". Lead to the conclusion: "we will be home by sunset." 2.
Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. 비 (c) (d) D EXERCISE 1.12.2: Proving arguments are valid using rules of inference. → P→ (q^r) -q -P (p^q) →r -r 9 :-P (pvq) →r p Ar pvq -pvr -q p→q r-u par q^u Feedback?
