Star 3

Drawn 98 times in 525 draws against 75.0 expected, +2.87σ. Testing all 7 numbers at once means about 0.1 should look this way by luck alone, so the threshold tightens to 1.4e-3 and this does not pass it.

Nothing here predicts the next draw. A number’s history is a record of a fair machine’s past, and the machine keeps none of it: 3 is drawn with probability 1/7 tonight whatever it did last week.
