Problem 6
7. A chief of detectives had three likely candidates for an opening in his department. To test their powers of reasoning, he pulled out a red and black marker and told them, "I am going to either make a red or black mark on each of your foreheads. At least one will be black. Without any help other than your own reasoning skills, I want you to determine the color of the mark on your own forehead. The first to do this and give me a satisfactory explanation at how you arrived at a conclusion will get the job."He then blindfolded the candidates and proceeded to put a black mark on each of their foreheads. After he removed the blindfolds, the three stared at each other for a few seconds, each seeing that the other two marks were black, then one of the candidates said, "I have a black mark."
How did the candidate arrive at this conclusion?
