This is lesser than the chances of flipping a standard coin 2,800 moments in a row and observing tails every time.
Even so, this estimate ignores sizeable empirical evidence about human behaviour and psychology. It naively assumes Everybody obtaining a ticket has an equivalent chance of selecting Every in the 28,989,675 attainable variety mixtures.

Could foul Enjoy be associated?
The fact that 433 profitable tickets were sold is much from convincing proof of any wrongdoing. It could be appealing to know the way Many of us purchased this very same pattern of quantities in past weeks, or which other combos also catch the attention of various hundred ticket income.
