That is smaller sized than the chances of flipping a standard coin 2,800 times in a very row and seeing tails every time.
On the other hand, this estimate ignores significant empirical evidence about human conduct and psychology. It naively assumes each person getting a ticket has an equivalent chance of selecting Every single with the 28,989,675 possible number combinations.
