This is certainly scaled-down than the likelihood of flipping a typical coin two,800 situations inside of a row and viewing tails each time.

Could foul Engage in be associated?

There in many cases are accusations when outstanding lottery effects are announced, Probably most infamously when FC Barcelona legend Xavi was declared the winner of a private lottery shortly just after moving to Qatar.
