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.

21. Let the following predicates be given. The domain is all computer science classes. I(r) = "x is interesting." U(x) = "x is useful." H(x, y) = “x is harder than y." M(x, y) = “x has more students than y." (a) Write the following statements in predicate logic. i. All interesting CS classes are useful. ii. There are some useful CS classes that are not interesting. iii. Every interesting CS class has more students than any non- interesting CS class. (b) Write the following predicate logic statement in everyday English. Don't just give a word-for-word translation; your sentence should make sense. (3)[I(x) A (Vy)(H(x,y)→ M(y, x))] (c) Formally negate the statement from part (b). Simplify your negation so that no quantifier lies within the scope of a negation. State which derivation rules you are using. (d) Give a translation of your negated statement in everyday English.

2. Let P(x) be "x is a student in this class," Q(x) be “x knows how to write programs in Python," and R(x) be “x can get a good job," where the domain of x consists of all people. Write the following argument in argument form and use the rules of inference to show that the argument is valid. Tom is a student in this class. Tom knows how to write programs in Python. Everyone who knows how to write programs in Python can get a good job. Therefore, some student in this class can get a good job.
How can we make a truth table ?
