Where it lands in a sorted draw
Sort a draw and 15 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 26 of the other 26 numbers; chance expects about 26 such strangers by now. Every pair →
How many people play it
Under the crowd model, 15 is picked about 1.22× as often as an indifferent choice — 14th most popular of 27. 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: 15 is drawn with probability 1/27 tonight whatever it did last week.
