Probabilities in a riddle involving axiom of choice
asked Dec 9 '13 at 16:16 Denis
（Denis質問）
I think it is ok, because the only probability measure we need is uniform probability on {0,1,…,N?1}, but other people argue it's not ok, because we would need to define a measure on sequences, and moreover axiom of choice messes everything up.
（Pruss氏）
The probabilistic reasoning depends on a conglomerability assumption, ・・・and we have no reason to think that the conglomerability assumption is appropriate.
（Huynh氏）
If it were somehow possible to put a 'uniform' measure on the space of all outcomes, then indeed one could guess correctly with arbitrarily high precision, but such a measure doesn't exist.

mathoverflowは時枝類似で
・Denis質問でも、もともと”but other people argue it's not ok, because we would need to define a measure on sequences, and moreover axiom of choice messes everything up.”
　となっています。Denisの経歴を見ると、彼は欧州の研究所勤務で、other peopleは研究所の確率に詳しい人でしょう
・Pruss氏とHuynh氏とは、経歴を見ると、数学DRです。両者とも、このパズル（＝riddle）は、可測性が保証されていないと回答しています

P2
Remark. When the number of boxes is finite Player 1 can guarantee a win
with probability 1 in game1, and with probability 9/10 in game2, by choosing
the xi independently and uniformly on [0, 1] and {0, 1,..., 9}, respectively.

Sergiu Hart氏は、ちゃんと”シャレ”が分かっている（関西人かもｗ）
Some nice puzzles Choice Games と、”おちゃらけ”であることを示している
かつ、”P2 Remark.”で当てられないと暗示している
また、”A similar result, but now without using the Axiom of Choice.GAME2”
で、選択公理なしで同じことが成り立つから、”選択公理”は、単なる目くらましってことも暗示している
