I don't believe so, the YouTuber standupmaths has an episode on a a three sided coin (die) which is equally likely to land on its edge as either face. They blackboard two theories on what ratio the coin should have, test them both extensively, do proper statistics, and conclude that neither is right and the answer must be somewhere in between.

They are currently encouraging viewers to try a bunch of different values and come up with an experimentally derived result.
