This really is smaller sized than the chances of flipping an average coin 2,800 occasions within a row and seeing tails each time.
However, this estimate ignores sizeable empirical evidence about human conduct and psychology. It naively assumes All and sundry paying for a ticket has an equal prospect of selecting Each individual of the 28,989,675 achievable variety mixtures.
