Using propositional logic, write a statement that contains the propositions p, q, and r that is true when both p → q and q ↔ ¬r are true and is false otherwise. Your statement must be written as specified below. (a) Write the statement in disjunctive normal form. (b Write the statement using only the ∨ and ¬ connectives.

(a) use the logical equivalences p → q ≡∼p ∨ q and p ↔ q ≡ (∼p ∨ q) ∧ (∼q ∨ p) to rewrite the given statement forms without using the symbol → or ↔, and (b) use the logi- cal equivalence p ∨ q ≡∼(∼p∧ ∼q) to rewrite each statement form using only ∧ and ∼. * p∨∼q→r∨q
a. Define what it means for two logical statements to be equivalent b. If P and Q are two statements, show that the statement ( P) л (PvQ) is equivalent to the statement Q^ P c.
