”if i is chosen uniformly independently of that strategy”
のindex iについてww
これ下記の”Alexander Pruss Dec 19 '13 at 15:05 ”の抜粋なw
以下の応答を嫁めw(^^
要するに、力点は、But以下の文にあるってことと
前文の”if i is chosen uniformly independently of that strategy”の部分が未証明だってことよw

The Modification
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. a

Let's go back to the riddle. Suppose u ̄ is chosen randomly. The most natural option is that it is a nontrivial i.i.d. sequence (uk), independent of the random index i which is uniformly distributed over [100]={0,...,99}.
In general, Mj will be nonmeasurable (one can prove this in at least some cases). We likewise have no reason to think that M is measurable. But without measurability, we can't make sense of talk of the probability that the guess will be correct.

Our choice of index i is made randomly, but for this we only need the uniform distribution on {0,…,n}. It is made independently of the opponent's choice.
