In theory it is very possible for a person to guess on every T/F question and get 100% correct. As the number of people taking the test increases the probability that the overall score is 50% approaches 100%. Gambling casinos show these theories to be true every day.

Dan,
First, I have a math degree.

Sigh...if you wanna play dueling degrees I'm afraid you're not gonna come out too well. So let's just stick to the point, OK?
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.
And since you live in Nevada howzabout you put $100 on 00 for me, OK? Keep doing it until I win!
