Where it lands in a sorted draw
Sort a draw and 8 has a favourite seat — chance gives a large number the high positions more often. That is the shape of sorting, not of the machine.
Never drawn alongside 9 of the other 9 numbers; chance expects about 9 such strangers by now. Every pair →
How many people play it
Under the crowd model, 8 is picked about 1.48× as often as an indifferent choice — 2nd most popular of 10. 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: 8 is drawn with probability 1/10 tonight whatever it did last week.
