This is often scaled-down than the likelihood of flipping a typical coin two,800 instances in a row and observing tails each and every time.
Nevertheless, this estimate ignores considerable empirical proof about human behaviour and psychology. It naively assumes Everybody paying for a ticket has an equal probability of choosing Each and every of the 28,989,675 feasible amount mixtures.

There are often accusations when extraordinary lottery effects are announced, Most likely most infamously when FC Barcelona legend Xavi was announced the winner of A non-public lottery Soon following transferring to Qatar.
