Bi-conditional question

fl7dqf

I just got a question wrong because I was confused about bi-conditionals so I just want to clarify

If A<----> B, that does NOT mean that B<--->A, right?

The contrapositive of a bi-conditional in the form A<----->B is /A<---->/B

Is this right?

Yes, that is correct.

A<----> B and this B<--->A are the same. A biconditional can be read forward or backward. As someone who didn't study logic in school, I found it helpful to look up real world examples online and then come up with my own examples that apply to my everyday life. You wrote the contrapositive statement correctly. I hope this helps.
