Not really. Here's a simple way to think about it. Consider the set of all possible sequences of exactly N characters typed by the monkeys, where N is much greater than the size of his complete works. Let n be the number of different characters that can be appear at any give location in one of those sequences. Consider every single location in any of those sequences where you could find a complete copy of Shakespeare's version of those works could be found. For each such location, there are n^2 other sequences which are identical to that sequence, except that they contain the alternative version of that sentence in the corresponding location, followed by two random letters. In addition, there's two locations near the end of an N-character sequence where you could find the start of the shorter version, but could not find the start of the longer version, because there's not enough room. I think there's some double counting here, because you could have sequences where the two "random characters" happen to be the first two characters of another instance of the shorter sequence - but for N >> the size of the complete works, I think the factor of n^2 dominates all other differences. > Obviously, I haven't a clue about the math involved here so it probably > would have been better put, "should a pack of monkeys produce the > complete works of Shakespeare then there is a likelyhood they also > produced the complete works of the monkees". "The Monkees" ran for two seasons, with a total of 58 episodes, In addition, "Between 1966 and 1970, The Monkees released 185 songs on 9 stereo albums, 5 mono albums, and 9 non-LP singles." <http://en.wikipedia.org/wiki/The_Monkees>. Shakespeare is credited with "38 plays, 154 sonnets, and a variety of other poems" <http://en.wikipedia.org/wiki/Shakespeare_bibliography>. I have no idea how to even estimate the size in characters of either set of "complete works", therefore I have no idea which is shorter. As I've shown above, even a small difference in the total length makes a huge difference in the likelihood of generating the sequence randomly.
