Problem 1.3. (a) Verify by truth table that ( P Q ) V(QP) (1.2) is valid (b) A propositional statement is satisfiable if and only if there is an assignment of truth values to its variables which make the statement true. Explain why PE-P (1.3) is not satisfiable. (c) A set of propositional formulas P, ..., Pk is consistent if and only if there is an environment in which they are all true. Write a formula, S, so that the...

1. Use the DPP to decide whether the following sets of clauses are satisfiable. (a) {{¬Q,T},{P,¬Q},{¬Q,¬S},{¬P,¬R},{P,¬R,S},{Q,S,¬T},{¬P,S,¬T},{Q,¬S},{Q,R,T}} (b) {{¬Q,R,T},{¬P,¬R},{¬P,S,¬T},{P,¬Q},{P,¬R,S},{Q,S,¬T},{¬Q,¬S},{¬Q,T}} 2. Decide whether each of the following arguments are valid by first converting to a question of satisfiability of clauses (see the Proposition), and then using the DPP. (Note that using DPP is not the easiest way to decide validity for these arguments, so you may want to use other methods to check your answers) (a) (P → Q), (Q → R),...
Check is 2-CNF satisfiable? Return one of its satisfying assignments.
The input is a Boolean formula in 2-CNF, given as a string of symbols.Example: p /\ (p -> q) /\ (p -> ~r) /\ (~r \/ ~s) /\ (s \/ ~q)1) check whether the given 2-CNF is satisfiable.2) given a 2-CNF, report that it is not satisfiable or return one of its satisfying assignments.Solution in Python3For the first task, you should implement a function called is_satisfiable, which takes the string with the 2-CNF as an argument and returns either True (satisfiable) or False (not satisfiable). The second task...

READ BEFORE YOU START: Solve each of the following question using 3 methods: pricing formulas, a financial calculator, and Excel. When calculating using the pricing formula (e.g. Price of perpetuity P = C/r), please write the original formula and the steps where you plug in the number for each variable, and your final answers. When solving via a financial calculator, please indicate the inputs and output variable (e.g. PMT, N, PV, I/Y, and FV). When solving it using Excel, learn...

Consider the following arguments. If an argument is valid, then present a proof sequence; otherwise, prove that the argument is invalid. You are forbidden to use truth tables to justify your answers (but, you may use them otherwise). ((p → r) ∨ (q → r)) → ((p ∨ q) → r) ((q → r) ∧ (p → (q ∨ r))) → (p → r) ((p → (q ∧ r)) ∧ (s → r) ∧ (s → t)) → (t →...
