Where it lands in a sorted draw
Sort a draw and 10 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.
It has shared a draw with every one of the other 51 numbers; chance expected about 2 still unmet by now. Every pair →
How many people play it
Under the crowd model, 10 is picked about 1.41× as often as an indifferent choice — 5th 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: 10 is drawn with probability 5/52 tonight whatever it did last week.
