Subject: RE: Prob/Stats brain twister. Can anyone figure this out?
Body:

Maybe a more interesting question would be what's the longest sentence someone could make without using a comma, colon or semicolon?

Otherwise, one could consider sentences like: "The list of all possible lists of english words is as follows "apple","apple,aardvark","apple,aardvark,apple"..."

It should be pretty clear that there are an infinite number of sentences of that form.

If we go with the exclusion I put above then we would get sentences of the form

(+)

With modifiers, I could see the standard sentence being as many as 20 words long.

Let's say that there are 100,000 english words.

(10^5)^20=10^100 sentences. This is probably an overestimation though as you can't use every word as every part of speech. Assuming that each spot only has about 20% of all words available to it, then you get

(2*10^4)^20=~10^86 sentences.
