The inverse of the conditional \(p \rightarrow q\) is \(\neg p \rightarrow \neg q\text{.}\) The contrapositive of this new conditional is \(\neg \neg q \rightarrow \neg \neg p\text{,}\) which is equivalent to \(q \rightarrow p\) by double negation.

2020年11月28日 · If a conditional statement is \(p\rightarrow q\) (if \(p\) then q), then the contrapositive is \(\sim q\rightarrow \sim p\) (if not q then not p). converse: If a conditional statement is \(p\rightarrow q\) (if \(p\), then \(q\)), then the converse is …

In logic and mathematics, contraposition, or transposition, refers to the inference of going from a conditional statement into its logically equivalent contrapositive, and an associated proof method known as § Proof by contrapositive. The contrapositive of a statement has its antecedent and consequent inverted and flipped. Conditional statement .

2024年8月3日 · The contrapositive of the conditional statement is “If not Q then not P.” The inverse of the conditional statement is “If not P then not Q .” We will see how these statements work with an example.

The contrapositive statement for “If a number n is even, then n 2 is even” is “If n 2 is not even, then n is not even. Example: The converse statement for “If a number n is even, then n 2 is even” is “If a number n 2 is even, then n is even. Mathematical representation: Conditional statement: p ⇒ q. Contrapositive statement: ~q ⇒ ~p

2021年1月19日 · The contrapositive of p -> q is the proposition ~q -> ~p. The inverse of p -> q is the proposition ~p -> ~q . By the following table, we can identify the values of Converse, Contrapositive, and Inverse:

Contrapositive is a statement formed by negating both the hypothesis and conclusion (p q) and also then interchanging these negations (~ q ⇒ ~p). Example : the statement ‘A triangle is a threesided polygon’ is true; its contrapositive, ‘A polygon with greater or less than three sides is not a triangle’ is true too.

For a conditional statement p → q, Its converse statement (q → p) and inverse statement (∼p → ∼q) are equivalent to each other. p → q and its contrapositive statement (∼q → ∼p) are equivalent to each other. Was this answer helpful?

2019年2月18日 · The contrapositive of p --> q is ~q --> ~p. It turns out that any conditional proposition ("if-then" statement) and its contrapositive are logically equivalent . In our example, the contrapositive of "If X is 2 then X is an even number" would read, "If X is NOT an even number then X is NOT 2."

Suppose you have the conditional statement [latex]{\color{blue}p} \to {\color{red}q}[/latex], we compose the contrapositive statement by interchanging the hypothesis and conclusion of the inverse of the same conditional statement.
