One greatly circulated estimate this 7 days assumed there were about ten million ticket profits, and claimed the possibilities had been as little as “a person out of one accompanied by 1,224 zeros” – A very absurd amount. This really is lesser than the likelihood of flipping a standard coin 2,800 moments in a row and viewing tails when.
