a completed wait — darker is longer the wait still running — a lower bound, not a finished gap
Where it lands in a sorted draw
Sort a draw and 9 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
Never drawn alongside 1 of the other 51 numbers; chance expects about 0.8 such strangers by now. Every pair →
How many people play it
Under the crowd model, 9 is picked about 1.48× as often as an indifferent choice — 2nd most popular of 52. 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: 9 is drawn with probability 6/52 tonight whatever it did last week.
