Best ResponseYou've already chosen the best response.1so you do have some idea, cool! 3!4!4!2! are the total ways to park those colored cars, but now you have one bunch of red cars, one bunch of blue cars, and so on.. that you can arrange among themselves. how many bunches of cars are there?

Best ResponseYou've already chosen the best response.1thats because 3 red cars parked first is a different way than 3 rd cars parked last!

Best ResponseYou've already chosen the best response.1now see if you get the total ways as \(4! \times (3!4!4!2!)\)
