Question

The second statement is the what of the first?

Answer 1

Answer:

  contrapositive

Step-by-step explanation:

The converse statement would be ...

  b ⇒ a

The contrapositive swaps the parts and negates them both:

  ¬b ⇒ ¬a . . . . . matches your given statement

The inverse negates both parts:

  ¬a ⇒ ¬b

A contradiction arises when the implication is false: a is true and b is false.
