This is often scaled-down than the chances of flipping a normal coin two,800 occasions in a very row and seeing tails whenever.
However, this estimate ignores significant empirical evidence about human behaviour and psychology. It naively assumes Every person paying for a ticket has an equivalent opportunity of selecting Each and every on the 28,989,675 doable range combos.

Could foul Perform be concerned?
