within that range, then,
and only then p is the frequency with which the As are
Q in the long run, or in other words, is the probability that
an A will be Q. Of course, we cannot say at any time
when that time will be or has been after which the value of the ratio
in the evergrowing tally wiil never leave that range of values. For
if we could do so, that would constitute a law in the succession
and the occurrences would not be independent.
But nevertheless the time will come, supposing
the occurrences are independent.
There must be some ultimate frequency; for
otherwise there would be a law of alternation
of some kind in the succession.
