If you ask a knight (True) about a Joker's answer (random), then she can't answer because she doesn't know? Does this give a NaN response or is it not allowed?

I looked at similar questions and couldn't find something directly addressing the problem. Which is odd because the standard answer to the simplest knight/knave problem (no joker) is to ask what the others response is

It could be any of:

  • the knight gives a third answer (like "I don't know")
  • the knight refuses to answer
  • the knight randomly picks what the joker would say in the hypothetical, and answers appropriately
  • this type of question is not allowed

It depends on the specific puzzle-setter. There is no universal standard for "knights and knaves" puzzles.
