Conditional statement : If an animal is a cat, then it has four paws.Converse: If an animal has 4 paws, then it is a cat.There are other animals that have 4 paws that are not cats, so the converse is falseInverse: If an animal is not a cat, then it does not have 4 paws.There are animals that are not cats that have 4 paws, so the inverse is false.Contrapositive: If an animal does not have 4 paws, then it is not a cat; TrueCats have 4 paws, so the contrapositive is true.If a statement’s truth value is false, give a counterexample.If an even number greater than 2 is prime, then 5 + 4 = 8.An even number greater than 2 will never be prime, so the hypothesis is false. 5 + 4 is not equal to 8, so the conclusion is false. However, the conditional is true because the hypothesis is false.{Note : If the hypothesis is false, the conditional statement is true, regardless of the truth value of the conclusion}
