A Contrapositive statement is logically equivalent.
The conditional statement "If A then B" is equivalent to "Not B or A" So, the inverse of "If A then B" is the inverse of "Not B or A" which is "Not not B and not A", that is "B and not A",
A conditional statement
That is correct.
conditional statement
It is the biconditional.
Contrapositive
a conditional and its contrapositive
The conditional statement "If A then B" is equivalent to "Not B or A" So, the inverse of "If A then B" is the inverse of "Not B or A" which is "Not not B and not A", that is "B and not A",
This is not always true.
The statement "if not p, then not q" always has the same truth value as the conditional "if p, then q." They are logically equivalent.
An obverse statement is logically equivalent.
An inverse statement is formed by negating both the hypothesis and the conclusion of a conditional statement. For example, if the original conditional statement is "If P, then Q," the inverse is "If not P, then not Q." Inverse statements can help analyze the truth values of the original statement and its contrapositive, but they are not logically equivalent to the original statement.
Negating the hypothesis and conclusion of a conditional statement forms the contrapositive of that statement. If the original conditional is "If P, then Q" (symbolically, P → Q), the contrapositive is "If not Q, then not P" (¬Q → ¬P). Importantly, a conditional statement and its contrapositive are logically equivalent, meaning they are either both true or both false.
The converse of an inverse is the contrapositive, which is logically equivalent to the original conditional.
The equivalent of an inverse statement is formed by negating both the hypothesis and the conclusion of a conditional statement. For example, if the original statement is "If P, then Q" (P → Q), the inverse would be "If not P, then not Q" (¬P → ¬Q). While the inverse is related to the original statement, it is not necessarily logically equivalent.
The statement "If not q, then not p" is logically equivalent to "If p, then q."
This would be logically equivalent to the conditional you started with.
