Determine whether the following is valid or invalid Look if

Determine whether the following is valid or invalid:

Look, if the check bounced, then you\'re right: Two things happened. First, we\'d owe a penalty. And second, our records would be out of whack. Now, if our records are out of whack or if we pay a penalty--either way--then we\'re in big trouble, just like you said. The check isn\'t gonna bounce, though. So relax. We\'re not in any trouble.

Solution

This is valid

Only if cheque bounces penalty is owed, and records would go out of whack.

So negation of cheque bouncing makes us relax.
