Study Notes

A conditional statement is expressed in "if then" form, linking a hypothesis to a conclusion.
The hypothesis refers to the "if" part of the conditional statement, setting the condition for the conclusion.
The conclusion represents the "then" part, which follows if the hypothesis holds true.

Counter Example

A counter example demonstrates a scenario where the hypothesis is true but the conclusion is false, disproving the conditional statement.

Variations of Conditional Statements

The converse of a conditional statement is formed by switching the hypothesis and conclusion, represented as "if q, then p."
The inverse involves negating both the hypothesis and conclusion, expressed as "if not p, then not q."
The contrapositive switches and negates both parts of the conditional statement, formulated as "if not q, then not p."

Biconditional Statement

A biconditional statement occurs when both the conditional statement and its converse are true, typically expressed as "p if and only if q."
