This is often more compact than the chances of flipping a normal coin two,800 occasions inside of a row and viewing tails when.
Nonetheless, this estimate ignores sizeable empirical proof about human conduct and psychology. It naively assumes Everyone getting a ticket has an equivalent prospect of choosing Every in the 28,989,675 attainable variety mixtures.
