Of three men, one man always tells the truth, one always tells lies, and one answers yes or no randomly. Each man knows which man is who. You may ask three yes/no question to determine who is who. If you ask the same question to more than one person you must count it as question used for each person whom you ask. What three questions should you ask?
Update: I was very embarrassed last night when I realized that my answer was incorrect. I’ll be sure to post an answer when I figure it out.
