#2 is really only difficult because it's easy to misinterpret the rules. Random doesn't randomly answer yes or know, he randomly decides whether to answer truthfully or falsely. So for example if you ask the recursive question "are you answering this current question truthfully" he will answer yes either way. Or rather, his word for yes. Once that rule is clear, the puzzle is pretty straightforward.
