1 broadly circulated estimate this 7 days assumed there have been about 10 million ticket income, and claimed the probabilities were being as small as “a single out of one followed by 1,224 zeros” – a truly absurd number. This can be more compact than the likelihood of flipping a typical coin two,800 situations inside of a row and observing tails whenever.
Even so, this estimate ignores significant empirical proof about human behaviour and psychology. It naively assumes each person obtaining a ticket has an equal prospect of selecting each on the 28,989,675 feasible range combinations.
