Where it lands in a sorted draw
Sort a draw and 25 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 3 of the other 52 numbers; chance expects about 7 such strangers by now. Every pair →
How many people play it
Under the crowd model, 25 is picked about 1.22× as often as an indifferent choice — 15th most popular of 53. 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: 25 is drawn with probability 5/53 tonight whatever it did last week.
