Asking the Right Questions to Solve the Riddle of Three People in One Room

[PhDorBust]

so you have room, and in said room you have three people...one always tells the truth, one always lies, and one sometimes tells the truth and sometimes lies.

you can ask three questions, to any of the individuals, but no more than three. IE, if you ask one person three questions, you have no more questions. You can ask each one question, or one person two questions, and one person one...still with me?

which questions to do ask to find out who is who... questions do not have to have yes/no answers, can be anything.
