I agree with the rest of what you wrote.

Well, maybe you should go back & reread my posts, pay attention to this:

Probability does not apply to a *single* random test taker. This is a fundemental concept. A single random test taker could get all, some, or none right in a 100 question T/F test and his results can not be predicted by the laws of statistics. Also, as Mark said, for N large we should expect SOME guessers to get 100% correct. But for N large the guessers tend to converge on a score of 50% correct with a probability approaching 1.

I would suggest you go back to YOUR original post & reword that to make it fit the mathematics that we both seem to know so well - I suggest a few sprinkles of "on average", "likely expected outcome", and like that.
