and left-handed and right-handed dice go in different directions (and apparently the poles of a d100 are less likely to show up).
but the difference goes deeper than that
A weird trick of psychology to view d100 outcomes as linear, in that "30 = hit, 31 = miss" is interpreted as "close call" when in reality the numbers assigned are arbitrary.
Suppose there are two systems: a 100 sided die, and a hat with 100 papers with a unique name on each one. Suppose that we know that one of the systems is biased and will not function properly. We roll the die 5 times and get [2,4,5,1,3]. We then pick a paper from the hat 5 times (replacing the one we've picked each time before the next pick) and get [Stacy, Becky, Chad, Tom, Bill]. What's the probability that the die is biased? And the hat?
