This can be smaller than the likelihood of flipping a standard coin 2,800 periods within a row and looking at tails each and every time.
Having said that, this estimate ignores significant empirical evidence about human behaviour and psychology. It naively assumes All and sundry purchasing a ticket has an equal likelihood of selecting Just about every of your 28,989,675 possible quantity combinations.
