Reading the draws and working out what chance predicts.
In New York Lotto under the 6/59 + 1/55 · Jan 2010 – Oct 2010 rules — 83 draws, 6 from 1–59 (an earlier era).
Drawn 10 times in 83 draws against 8.4 expected, +0.57σ. Each draw is independent: after 20 draws away it is exactly as likely tonight as a number drawn yesterday.
Drawn 10 times in 83 draws · average wait 6.9 draws · longest completed wait 19 · waiting 20 draws now
a completed wait — darker is longer the wait still running — a lower bound, not a finished gap
Sort a draw and 29 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
Seen most often with these — chance gives every partner about 0.9 shared draws, and the leaders are simply the ones that came out ahead this time.
Never drawn alongside 25 of the other 58 numbers; chance expects about 24 such strangers by now. Every pair →
Under the crowd model, 29 is picked about 1.22× as often as an indifferent choice — 15th most popular of 59. That changes nothing about whether it comes up, and everything about how many ways a jackpot on it would be shared.

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: 29 is drawn with probability 6/59 tonight whatever it did last week.
