Two statement forms are logically equivalent if, and only if, their resulting truth tables are identical for each variation of statement variables. p q and q p have the same truth values, so they are logically equivalent.
Q. What is contingency in philosophy of religion?
In religion and theology, contingency often marks the fundamental difference between the Creator and creation: Everything created could be otherwise, while God could not not exist. In medieval terms: God is the one absolutely necessary being (ens per se necessarium).

Q. What is meant by propositional logic?
Propositional logic, also known as sentential logic and statement logic, is the branch of logic that studies ways of joining and/or modifying entire propositions, statements or sentences to form more complicated propositions, statements or sentences, as well as the logical relationships and properties that are derived …
Q. Is a proposition which is always false?
A compound proposition is called a contradiction if it is always false, no matter what the truth values of the propositions (e.g., p A ¬p =T no matter what is the value of p. Why?). Finally, a proposition that is neither a tautology nor a contradiction is called a contingency.
Q. What is the negation of a conjunction?
Negation of a conjunction Since at least one of them must be false, then their conjunction would likewise be false. Negating said conjunction thus results in a true expression, and this expression is identical to the first claim.
Q. What are other forms of conditional propositions?
Variations on the Conditional – The Converse, Inverse, and Contrapositive are variations on the Conditional proposition. Both the hypothesis and the conclusion are true, so the Conditional Proposition is True.
Q. What are the different forms of conditional propositions?
Conditional Propositions. A proposition of the form “if p then q” or “p implies q”, represented “p → q” is called a conditional proposition. For instance: “if John is from Chicago then John is from Illinois”. The proposition p is called hypothesis or antecedent, and the proposition q is the conclusion or consequent.
Q. What is a proposition in math?
A proposition is a statement that is either true or false. In our course, we will usually call a mathematical proposition a theorem. A theorem is a main result. A proposition that is mainly of interest to prove a larger theorem is called a lemma.
