Question

Answer plz !! Whats the contrapositive ?

Answer 1

Answer:

It should be the first answer.

Step-by-step explanation:

The first answer says "If Nemo is a fish, then he swims". That makes sense. Then the second one says "If Nemo does swim, then he is a fish". That would make sense, but if my name was Nemo, I can swim. That doesn't mean I'm a fish. The the third one says "If Nemo is not a fish, then he doesn't swim". That doesn't make sense. Say my name is Nemo. I'm not a fish. I can swim though!

Answer 2

Answer:

If Nemo is a fish, then he swims.

Step-by-step explanation:

The contrapositive is

If A implies B then not B implies not A.

If Nemo does not swim, then he is not a fish, so:

The contrapositive is:  If Nemo is not not a fish then he does not not swim.

= If Nemo is a fish, then he swims.
