Math Dr. Tony Huynh氏も分かっている ”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.”
つまり ”If it were somehow possible to put a 'uniform' measure on the space of all outcomes”が実現できれば なのだが 'uniform' measure＝一様分布 （「一様分布」は、>>67の非正則事前分布の説明に出てくるね）
