3. Let S(x) be the statement “x is a student," P(x) be the statement “x is a professor," and Q(x, y) be the statement “x asked a question to y." If the domain of x and y consists of all people, express each of the following sentences in terms of S(x), P(x), Q(x,y), quantifiers, and logical operators. Example: Some student has asked every professor a question. Answer. 3x(S(x) A Vy(P(V) → Q(x,y))) a. Every professor has been asked a question by some student. b. There is a student who has never asked a question to a professor. c. There is a professor who has been asked a question by exactly one student. d. There are two different students who have asked each other a question.

There is a professor who has never been asked a question by any student. c. There is a student who has asked a question to exactly one professor. d. There are two different students who have asked each other a question.
So the statement TS is bijective iff T and S are bijective is correct then?
let D be the set of all students at a college. let M(x) be “x is a mathmajor.” write the following statements using quantifiers and logic symbols:a. all students are math majors.b. some students are math majors.c. no students are math majors
let P and Q be predicates on some domain of discourse D and define p = Vx (P(x)) → Vx (Q(x)) q = Vx ( P(x) → Q(x) ). Check all statements that must be true. O If q is true, then p is true. None of the other choices. If p is true, then q is true.
Rewrite each of the following so that the negation operator appears only within the predicates (for example, no negation is outside a quantifier or an expression involving logical connectives). Explain your results. ¬∀x∃y(P(x,y) ∧ Q(x,y)) ¬∃y(∃xR(x,y) ∨ ∀xS(x,y))
Question 6 Plz send hand written answer asap
Proficiency #8. Which of the following are logically equivalent to the statement -[(Vx E U) (¬p(x) V q(x))] if U is the set of all parrots, p(x) is the statement "x is talkative", q(x) is the statement “x is green" (Choose all that apply): I. There is an parrot who is not green and is talkative. II. No talkative parrots are green. III. All green parrots are talkative. IV. Not all parrots are not green. V. At least one talkative parrot is not green. VI. Not all talkative parrots are green.
Tarski World a g. Using the following predicates: square (x) is true if x is a square (otherwise it is false) star(x) is true if x is a star (otherwise it is false) circ(x) is true if x is a circle (otherwise it is false) shade (x) is true if x is shaded (otherwise it is false) next.to(x, y) is true if x and y are adjacent horizontally, vertically or diagonally. This relation is not reflexive for any object. For each of the statements below, determine whether the statement is true or false. You need not justify your response. 3xcirc(x) A shade(xr) Va shade(r) V ¬shade(r) Va square(r) → ¬shade(r) Vævy(star(r) A ¬shade(r) A next.to(x, y) → shade(y) ^ circ(y)) vr next.to(x, y) A shade(r) 3rvy next.to(r, y) A shade(r)
Negating Formulas with Nested Quantifiers De Morgan's laws allow to rewrite the negation of a disjunction or a conjunction in a logical equivalent formula where the negation appears in front of the atomic propositions and not in front of a compound proposition: -(a A b) = ¬a V ¬6 ¬(a v b) = ¬a ^ ¬b
(11) Let P be the statement: "For all a, b = Z, if a + b is divisible by 10, then a is divisible by 10 and b is divisible by 10." (a) Express P using logic symbols, denoting the set of all multiples of ten by T. (b) Find ¬P, in both logic symbols and in english. (c) Find the contrapositive of P. (d) One of P or P is true. Determine which one, and justify your answer.
