There are 20 cars in my building's parking lot. All of the cars are red or white. Also, all the cars are either 2-door or 4-door. 15 of them are red, 18 of them are 4-door, and 3 of them are 2-door and white. How many of the cars are 4-door and red?

Unless I am missing something the question does not make sense.

 

18 are  four-door which means that 2 are two-door.

So 3 cannot be 2-door and white.
