Why do you say that?

I'm not sure I follow wht this example has to do.

Do you have a cite to support this contention?

That's not my understanding of how the math works. Do you have any citation 
as evidence for this? Because if the letter 'a' doesn't show up after an 
*infinite* number of trials, you clearly don't have any probability for it 
to show up at all, and indeed that's what the math pages I've cited already say.
