Construct a truth table to decide if the two statements are equivalent~p ∧ ~q;Recall that P ∨ ¬ Q is the same as Q → P So the formula of the question is equivalent to ( Q → P) ∧ ( R → Q) ∧ ( P → R) Since implication is transitive (if A → B and B → C then A → C follows) this formula implies that P → Q (since P → R and R → Q ), and similarly it also implies that Q → R and R → PThe Truth Table for the compound proposition (p ∨ ￢ q) → (p ∧ q) p q ￢ q (p ∨ ￢ q) (p ∧ q) (p ∨ ￢ q) → (p ∧ q) T T F T T T T F T T F F F T F F F T F F T T F F Equivalent Propositions Two propositions are e quivalent if they always have the same truth value Example Show using a truth table that the conditional is

Recall that P ∨ ¬ Q is the same as Q → P So the formula of the question is equivalent to (Q → P) ∧ (R → Q) ∧ (P → R)Once the table is there, use the button "Show intermediate results" or "Hide intermediate results" to show or hide intermediate results in the table Since 21 you may enter more than one proposition at a time, separating them with commas (eg " P∧Q, P∨Q, P→Q")If P is false and Q is false, then P → (Q ∧ ¬ P) is true, because ¬ P ∨ (Q ∧ ¬ P) is true as above, since P is false, by the valuation rule for negation ¬ P is true, so the disjunction as a whole is true, because the former disjunct is true Notice what the material conditional is not saying it's not saying the consequent is true Nor is it saying that the antecedent makes the consequent true
