This is lesser than the probability of flipping an average coin two,800 moments in a very row and observing tails each and every time.
Nevertheless, this estimate ignores sizeable empirical evidence about human conduct and psychology. It naively assumes Every person buying a ticket has an equivalent prospect of selecting Just about every from the 28,989,675 doable quantity mixtures.

The truth that 433 successful tickets ended up sold is far from convincing evidence of any wrongdoing. It would be intriguing to understand how Many of us acquired this exact sample of figures in past weeks, or which other combos also attract quite a few hundred ticket gross sales.
