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 4 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 19 of the other 19 numbers; chance expects about 19 such strangers by now. Every pair →
How many people play it
Under the crowd model, 4 is picked about 1.34× as often as an indifferent choice — 6th most popular of 20. 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: 4 is drawn with probability 1/20 tonight whatever it did last week.
