There are questions for which you don’t know the answerability, so either the rules must be that questions asked are provably answerable, or else you are allowed to glean information from whether the god answers it or not.
Assuming that True and False do not know the future results of questions to Random, an example is a question to A (True) of “Would B say 1 + 1 = 2?” If B is False, it is answerable (with a ‘no’). If B is Random, it is unanswerable.
I interpreted it to mean that the question must be answerable with yes or no.

Provably answerable from your own knowledge.
