Page "Gambler's fallacy" Paragraph 20

Some lottery players will choose the same numbers every time, or intentionally change their numbers, but both are equally likely to win any individual lottery draw.

Copying the numbers that won the previous lottery draw gives an equal probability, although a rational gambler might attempt to predict other players ' choices and then deliberately avoid these numbers.

Low numbers ( below 31 and especially below 12 ) are popular because people play birthdays as their so-called lucky numbers ; hence a win in which these numbers are over-represented is more likely to result in a shared payout.
