Pr v q. Regarding the question about needing two "p" for the conclusion, the extra "p" is added in lines 6 for the Q case and in line 9 for the R case Note how this was done in the Q case In line 4 I started a subproof by assuming Q. As for the intuitiveness of it Think about when any of (P > R) V (Q > R) and (P ∧ Q) > R are false only when both P and Q are true but R is false;. A) p^q ^r The dual is p_q _r Just turn all the ^’s into _’s b) (p^q^r)_s The dual is (p_q_r)^s Just interchange ^’s and _’s c) (p_F)^(q_T) The dual is (p^T)_(q^F) Besides interchanging ^’s and _’s, be sure to interchange T’s and F’s, too 46 and 48 Construct truth tables for NAND and NOR p q p NAND q p NOR q T T F.

Now, our final goal is to be able to fill in truth tables with more compound statements which have more than just one logical connective in them Statements like q→~s or (r∧~p)→r or (q&rarr~p)∧(p↔r) have multiple logical connectives, so we will need to do them one step at a time using the order of operations we defined at the beginning of this lecture.

Solution for ^ q) V (p ^ r) p^ (q v r) = (p Social Science Anthropology. Two propositions p and q are called logically equivalent if and only if vp = vq holds for all valuations v on Prop In other words, two propositions p and q are logically equivalent if and only if p 㲗 q is a tautology We write p ≡ q if and only if p and q are logically equivalent We have shown that (¬p ⋁q) ≡ (p q). ¥ ì>8 ¹ B Ñ Ñ º Ñ v Ñ ¥>& Ñ>' Ñ / ì d>8¬'g q · é æ _* >8>R>/ Ñ Ñ Ñ Ñ>R>0 Ñ Ñ Ñ Ñ >R>1 Ñ Ñ Ñ Ñ>R>2 Ñ Ñ Ñ Ñ Ú Ñ ¡ >/8 ¦ ¡ ¤ L Z s ,< I A £ >08 ¦ b% >&>/>' ,< I A £ b"@1 3û K Z 8b & x0ð K m b í) b, l í ^ _0 ^ ¤0l q#Ý K S ~7º V ¼ w E ° S ~.

Then no matter whether p or q is the case, the truth of r must follow The division into cases method of analysis is based on the following logical equivalence p ∨ q → r ≡ (p → r) ∧ (q → r) The following truth table shows that p ∨ q → r and (p → r) ∧ (q → r) have the same truth values Hence, the two propositions forms. 11 PROPOSITIONS 7 p q ¬p p∧q p∨q p⊕q p → q p ↔ q T T F T T F T T T F F F T T F F F T T F T T T F F F T F F F T T Note that ∨ represents a nonexclusive or, ie, p∨ q is true when any of p, q is true and also when both are true On the other hand ⊕ represents an exclusive or, ie, p⊕ q is true only when exactly one of p and q is true 112.

Nov 05, 09 · Taken together, the statements indicate that q and r are both positive and p is negative If r a dn q are both positive fractions, say 1/2 and 1/4, and p is a negative integer (like 3), then the statement pqr. Writing out the truth table is one of the way If you want more rigorous answer, then we need definition Definition 1 Suppose A={p1, p2,, pn} is a set of propositional formulas and p is a propositional formula We will say that p is proposition.

Jan 01, 11 · You have a typo on the third line it's supposed to be "(¬P V ¬Q) V R" and then by DeMorgan's rule you get the 4th line ¬(P ∧ Q) V R Maybe that was bothering you?. Question P → Q Q → R ¬(p ∨ Q) _____ ∴ ¬r Right Now I Think It Is Valid Because Of De Morgan's Law Making ¬(p ∨ Q) Into (¬p∧¬q) And Then Getting ((¬p∧¬q) ∧(p→q) ∧(q → R))> ¬r But Not Really Sure Where To Go From Here Or How Exactly To Prove It Someone Said To Use A Truth Table But I Don't Get How The Truth Table Would.

Since column 5 and 8 are same Hence, p^ (q V r) and (p^ q) V (p ^ r) are logically equivalent.

(p ∨ q) → r ≡ (p → q) ∨ (p → r) could be valid or invalid I need to prove it using logical equivalences (can't use truth table) This is how far I've gotten by working with the right side p→(q v r) ¬p v (q v r) then commutative law (q v r) v ¬p then commutative law (r v q) v ¬p then associative law r v. Example 213 p_q!r Discussion One of the important techniques used in proving theorems is to replace, or substitute, one proposition by another one that is equivalent to it In this section we will list some of the basic propositional equivalences and show how they can be.
