Probabilities in a riddle involving axiom of choice - MathOverflow: edited Dec 9 '13 Denis
(抜粋)
In this context, does it make sense to say "guess the content of a box with arbitrarily high probability"? 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.

４）まとめ
まあ、英語圏では、これは
・”Probability is not defined here”（確率は定義されない）
・”But it is a good example illustrating the difference between arbitrarily large and infinite. ”
”As for the mathematicians, the unfortunate part is that no matter how large they make N, the probability is still 0 that their sequence matches its representative sequence at the N-th place.”
（「arbitrarily large」が可能無限、「infinite」が実無限な ）
・”In this context, does it make sense to say "guess the content of a box with arbitrarily high probability"? 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.”
（英語圏でも、落ちこぼれは”I think it is ok”だけど・・、分っている人は”it's not ok, because we would need to define a measure on sequences, and moreover axiom of choice messes everything up.”）

スレ主がまたサイコパスぶりを発揮してるねｗ
日本でも海外でも {0,1,…,N?1}の一様確率で数学的にＯＫ
むしろ数列上の測度が必要とかほざく奴は似非数学にかぶれた馬鹿
スレ主、貴様のことだ
