Ana wants to paint her dogs doghouse. She has 4 colors: Green, Maroon, Blue and Wheat. One color will cover the walls, and another color will be used for the trim. (For example, green walls with wheat trim = GW.) Which one of these answers show all of the possible color combinations? A. BW, BM, BG, BB, MW, MB, MG, MM, GW, GB, GM, GG B. GM, GB, GW, MG, MB, MW, BG, BM, BW, WG, WM, WB C. MM, MG, WB, WM, WG, BB, BG, BM, WB, GB, GM, GW

Let us take this one by one. One color can pair with three colors.   Green = Maroon, Blue, Wheat = GM, GB, GW Maroon = Green, Blue, Wheat = MG, MB, MW Blue = Green, Maroon, Wheat = BG, BM, BW Wheat = Green, Maroon, Blue = WG, WM, WB   So the combinations are:   GM, GB, GW, MG, MB, MW, BG, BM, BW, WG, WM, WB   Which is letter B.
