Somebody once asked one of these what the probability was that six was the last digit of pi. It came up with all sorts of responses, TENDING TO BE VERY, VERY WORDY. That's what I find most interesting. All of them incorrect. I didn't see humans give a correct answer, either.
I solved it quickly, but do a lot of math. The answer is zero. Since there is no last digit, there is zero chance six is it. But this is something I solved with mental pictures and only state with words.
