Let A, B, C be propositional variables, and let P and P, be the following compound propo- sitions: P : (AV B) → ¬C P2: ¬A + (BA C) Is the set {P, P2} a consistent set of propositions? Show your work. For this question, you may use either a truth table or a truth tree (using the official branching rules). If your answer is "YES', then give all truth assignments of A, B,C that support your answer, and briefly explain.

please answer with proper explanation and step by step solution. Question: Provide proofs for the following statements a.The full resolution inference rule (on Slide 37) holds for any k, n≥1. During the lecture, we show the proof for the simple resolution inference rule. You can use a similar approach. b.Horn clauses are closed under resolution: if you resolve two Horn clauses with complementary literals in the two clauses, you get back a Horn clause.

For (∃ x)(P(x,b)) Would an example of this being true if the domain was all the Avengers and x was green skin, then "b" being the Hulk would make this true. Am example of this being false would be: If the domain was all integers and x was positive, even integers and "b" was integers greater than zero.
please answer with proper explanation for right and wrong both options.
Write TRUE if the statement is true, otherwise, write FALSE.5. The negation of (P ∧ Q) =⇒ (P ∨ Q) is a contradiction.
Four mathematicians have a conversation, as follows: ALICE: I am insane. BOB: I am pure. CHARLES: I am applied. DOROTHY: I am sane. ALICE: Charles is pure. BOB: Dorothy is insane. CHARLES: Bob is applied. DOROTHY: Charles is sane. You are also given the following information: Pure mathematicians tell the truth about their beliefs. Applied mathematicians lie about their beliefs. Sane mathematicians' beliefs are correct. Insane mathematicians' beliefs are incorrect. With the preceding clues, classify the four mathematicians as applied or pure, and insane or sane. Briefly explain your logic.
If p’s status is unknown, q = T, r = F, give the truth value for: (p ∧ r) ↔ r Use ~ for negation.
Let p, q, and r be the propositions p: You started a new video game this week. q: You finished all its quests.r: You didn’t win the platinum trophy.Express each of these propositions as an English sentence.¬p → ¬q(p ∧ q) → (¬r)((¬p) → (¬q)) ∨ (q → (¬r))(p ∧ q) ∨ (¬q ∧ r)
Correct answer will be upvoted else Multiple Downvoted. Computer science. We should improve on this game a little. Officially, there are n members, the I-th member picked the number man-made intelligence. The victor of the game is such a member that the number he picked is novel (I. e. no other individual picked this number aside from him) and is insignificant (I. e. among all exceptional upsides of a the base one is the triumphant one). Your undertaking is to find the record of the member who dominated the match (or - 1 in case there is no victor). Ordering is 1-based, I. e. the members are numbered from 1 to n. You need to answer t autonomous experiments. Input The primary line of the input contains one integer t (1≤t≤2⋅104) — the number of experiments. Then, at that point, t experiments follow. The primary line of the experiment contains one integer n (1≤n≤2⋅105) — the number of members. The second line of the experiment contains n integers a1,a2,… ,an (1≤ai≤n), where…
