Is it:

If the grass does not grow too tall, then I did not mow the lawn??

**MathMate**, Friday, July 29, 2011 at 11:00pmHere is list of the four possibilities (source: (Broken Link Removed)

* statement: if p then q

* converse: if q then p

* inverse: if not p then not q

* contrapositive: if not q then not p

Your proposition is not one of them.

Let

p=I don't mow the lawn

q=grass grows too tall

The original statement is then

if p then q

The converse: if q then p

i.e. if the grass grows too tall, then I didn't mow the lawn.

You have proposed: if ~q then p

"If the grass does not grow too tall, then I did not mow the lawn" which is not one of the four usual variations.
