Let D(z) be "z is a day", S(r) be "r is sunny", R(r) be "x is rainy", M be "Monday", and I be "Tuesday". Using these predicate symbols and appropriate quantifiers, write each English language statement as a predicate wff. Note: The domain is the whole world. (a) Some days are sunny and rainy. (b) No day is both sunny and rainy. (c) It is always a sunny day only if it is a rainy day. (d) No day is sunny. (e) Monday was sunny; therefore every day will be sunny. (f) It rained both Monday and Tuesday. (g) If some day is rainy, then every day will be sunny.

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.

State which derivation rules you are using. (d) Give a translation of your negated statement in everyday English.
This proposition is a tautology: ((p→¬q)∧q)→¬p True or false I would appreciate step by step explanation
A student club holds a meeting. The predicate M(x) denotes whether person x came to the meeting on time. The predicate O(x) refers to whether person x is an officer of the club. The predicate D(x) indicates whether person x has paid his or her club dues. The domain is the set of all members of the club. The names of the members and their truth values for each of the predicates is given in the following table. Indicate whether each expression is true or false. If a universal statement is not true, give a counterexample. If an existential statement is true, give an example. Name M(x) O(x) D(X) Hillary T F Bernie F F Donald F F Jeb F Carly F F Ex (M(x) A D(x)
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.
