How many people play it
Under the crowd model, 30 is picked about 1.28× as often as an indifferent choice — 13th most popular of 41. 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: 30 is drawn with probability 5/41 tonight whatever it did last week.
