How many of the disjunctions p∨¬q, ¬p∨q, q ∨r, q ∨¬ r, and ¬q ∨¬ r can be made simultaneously true by an assignment of truth values to p, q, and r?
Please explain how to find that? thinking process!
How many of the disjunctions p∨¬q, ¬p∨q, q ∨r, q ∨¬ r, and ¬q ∨¬ r...
Given p is true, q is false, and r is false, find the truth value of the statement (q ^~r) ->~p.
Find the truth value of the statement. Assume that p and q are false, and r is true. 15) -(19) ►-9 A) True B) False Use a truth table to decide if the statements are equivalent. 16) q→P; - Vp A) Not equivalent B) Equivalent
Let p represent a true statement, while q and r represent false statements. Find the truth value of the compound statement.~[(~p ^ q) ^ r]
Question 12 Let p, q and r be simple declarative statements. Which alternative provides the truth values for the biconditional ‘?, of the compound statement provided in the given table? q ? p) and Hint: Determine the truth values of p ? r, q v r, (p ? r) ^ (q v r), q ? p, (q-p) rin separate columns before determining the truth values of TIFF FTF F F T
please in java or python truth tables for the following...please #1 p -> q q -> r therefor: p -> r #2 p -> (q or r) q and ~r Therefore: p #3 p or q (p and q) -> r q and ~r Therefor: ~p
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...
what is the truth value of (~ w and Q) or (P if ~ r) given that r is false 5/30 wess For questions 6-10, answer true, false or can't be determined because of insufficient information. What is the truth value of (w^q) v (p >~ r) given that r is false? 6. If (~bAc)- (av~ w) is false, then what is the truth value of aAc? 7. 8. Suppose mvrand rq are true statements. Ifq is true, then what...
number 3 please 3. (a) If pA~q is true, determine the truth values of p and q. (b) If~p Vq is false, determine the truth values of p and q 4. Write pAq as an equivalent statement without using the connective A
Find the dual of the equivalence without a truth table: p V (q → r) ≡ (p V q) → (p V r)
2. (a) Show that (PVQ) + R is not logically equivalent to (P + R) V(Q + R) using a truth table. (b) Is (PAQ) → R logically equivalent to (P + R) A( Q R )? If so, use a truth table to establish this. If not, show that it is false.
