The Sleeping Yuna Problem

Each of those little panels with Yuna in them is drawn individually. That’s dedication to the art form that only nutcases like Bill Watterson would appreciate.
- Ye Thuza: Rise and shine, Yuna! Because you were such an insufferable brat last week, I decided to carry out a devilish experiment on you.
- Yuna: Really?! But I don’t have any tentacle arms!
- Ye Thuza: It’s more of a mind game.
- Ye Thuza: In this experiment, the mad scientist – that’s me – puts the human guinea pig – that’s you – to sleep on Sunday. Once or twice, the test subject will be awakened, interviewed, and put back to sleep with an amnesia-inducing drug that makes her forget the awakening. A coin will be tossed to determine which experimental procedure to undertake: if the coin comes up heads, the test subject will be awakened and interviewed on Monday only. If the coin comes up tails, she will be awakened and interviewed on Monday and Tuesday. In any case, the experiment will end on Wednesday without any further interview.
- Ye Thuza: This means, it’s either Monday or Tuesday today. Now I ask you: what is your credence now for the proposition that the coin landed heads?gezeigt hat?
- Yuna: That’s easy! It’s 50%!
- Ye Thuza: Oh, is that so?
- Yuna: No, wait…! It’s a third! … Hmm…
- Ye Thuza: Even if I say that the coin is still lying on the kitchen table?
