Examples Take the statement "All red objects have color." This can be equivalently expressed as "If an object is red, then it has color." The contrapositive is "If an object does not have color, then it is not red." This follows logically from our initial statement and, like it, it is evidently true.The inverse is "If an object is not … Zobacz więcej In logic and mathematics, contraposition refers to the inference of going from a conditional statement into its logically equivalent contrapositive, and an associated proof method known as proof by contraposition. … Zobacz więcej Let: $${\displaystyle (A\to B)\land \neg B}$$ It is given that, if A is true, then B is true, and it is also given that B is not true.
