This can be lesser than the likelihood of flipping a standard coin 2,800 moments in a row and observing tails every time.
Even so, this estimate ignores sizeable empirical proof about human behaviour and psychology. It naively assumes Everyone getting a ticket has an equivalent prospect of choosing each from the 28,989,675 feasible amount combinations.

The likelihood of nine, 18, 27, 36, forty five and fifty four currently being drawn are exactly the same as, say, 1, eighteen, 19, 28, thirty and 46.
Nonetheless Many individuals would (wrongly) understand the latter sequence for being extra likely to arise at random.
The profitable quantities were all divisible by 9. Facebook/Phillipine Charity Sweepstakes Place of work
Usually, individuals have been shown to become remarkably inadequate judges of what a string of genuinely random numbers would look like. In actual fact, they may have even been outsmarted at uncomplicated probabilistic pattern-matching by the humble pigeon.
