| Thanks for the book link John. Inspired by Saturday's great study meeting with Timmy and John, I created a super simple probability test:|
With each refresh of the page, a news item about IBM stock appears, and 'Jim' tweets his mood. Jim has sold short against IBM stock, and thus tends to be sad when IBM is up, and happy when IBM is down. But his mood is effected by other things too, so his mood is not always determined by IBM stock news. What percentage of the time is John's mood determined by IBM stock news?
