Front

What is the definition of a conditional statement in logic?

Back

A conditional statement is an if-then statement that expresses a relationship between two propositions, where the first proposition (the hypothesis) implies the second proposition (the conclusion).

What is the inverse of a conditional statement?

Back

The converse of a conditional statement 'If P, then Q' is 'If Q, then P.'

Front

What is the contrapositive of a conditional statement?

Back

The contrapositive of a conditional statement 'If P, then Q' is 'If not Q, then not P.'

How do you identify the inverse of a statement?

Back

To identify the inverse, negate both the hypothesis and the conclusion of the original conditional statement.

Front

How do you identify the contrapositive of a statement?

Back

To identify the contrapositive, negate both the conclusion and the hypothesis of the original conditional statement and switch their places.
