I'm afraid not.  It allows you to say things about some imaginary "things"
you name A and B (i.e. it allows you to state generalities); it does not
allow you to say things about THE particular balls in THE particular basin.
 That's rather the point of the exercise, I should think.

To quote a distinguished logician, "YOu need to brush up on your logic." ;)
