>Of course, not all letters occur with the same frequency. If the typewriter noticed that the monkey typed a “Q”, then it could force the next letter to be “U” with a particular probability. Similarly for other letter pair combinations. One can imagine using some existing text as a model from which to calculate frequencies of letter pairs. How often is “t” followed by “h” ? by “a” ? One can also imagine that extrapolating such 2 letter patterns to n letter patterns can produce even better results.

Dang, that's scary. We just had that conversation here a few days ago (Baysian filtering, Benford's law, etc.). Great timing...
