This really is lesser than the likelihood of flipping a standard coin 2,800 situations in the row and looking at tails each and every time.
Having said that, this estimate ignores significant empirical proof about human conduct and psychology. It naively assumes Everybody purchasing a ticket has an equal possibility of choosing each on the 28,989,675 doable range combos.
