 Blog Entries: 5 Recognitions: Homework Help Science Advisor So let's define some properties: F: the car is fast Ch: the car is cheap S: the car is painted silver Co: the car is convertible Now can you make a logical expression which is true when she does buy the car? So I'm looking for something of the form: (F or Ch) and (F and ((not Co) or S). Also try to express the answer possibilities this way (as an example, number 1 would become: $(F \wedge \neg Ch) \vee (S \wedge Co)$). Once you have that, I will of course ask you if you can negate that expression.
 I doubt the OP has experience with formal logic, let alone symbolic logic, CompuChip.
