Where it lands in a sorted draw

Never drawn alongside 5 of the other 54 numbers; chance expects about 8 such strangers by now. Every pair →
How many people play it
Under the crowd model, 27 is picked about 1.22× as often as an indifferent choice — 15th most popular of 55. 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: 27 is drawn with probability 5/55 tonight whatever it did last week.
