3. The teacher said to the 3 students, “I will blindfold you and place a mark on each of your foreheads. Each of you will either have a black or white mark. When I tell you to take your blindfolds off, you are to raise your hand if you see a black mark on the foreheads of either of the other applicants. Then the first one who correctly tells the color of your own mark wins the game.” All three students raised their hands at the same time. One of them however came up with the correct color of her own mark. What color is her mark, and how did she figure it out?
