I wonder if the balls work by weights. For example 6 ball weigh less than the rest of them!

You're betting on a single instance, not that the numbers will repeat themselves. It's no more irrational to choose the numbers from last night than any other set. If the bet was that the numbers would repeat, it'd be different.

A similar incident occured on Aug. 10th 1958: On that day, the exact 6 numbers (out of 49) were picked in the German national lottery as one week before in the Dutch lottery.

someone is cheating?!

If you have documentary evidence of the other freak lottery occurence you mention I would love to get the information. i.e. When, where, who, evidence etc. I deal in cosmic probability. With thanks !

There are two errors in this report because the question to the experts appears wrongly worded and they should have corrected the question before responding. The phenomenon relates to a set of 6 numbers being identical to a set which has appeared in another draw. The actual set is unimportant and has already occurred in the past so the probability of a further set being that same set is 1 in 1,250.000 not in the trillions. Those astronomical probabilities would only be relevant if you'd nominated in advance the set which you predict will occur twice. The other error is the time frame. Why a month? Again it wasn't chosen in advance of the recent draw so a more practical question would be: what is the chance of the 6 numbers being identical to a set of 6 numbers which appeared already in the past year, or past 20 years. Then the probabilities start to reduce as the denominator increases from 1 to the past number of draws to be considered.

I saw the incident mentioned years ago in a German text book on statistics and probability. In June of this year, German news magazine Stern ran an article about a different strange outcome of a lottery drawing when no less than 26 players picked the right 6 numbers. The magazine quotes a spokesman for the state lottery who also mentions the 1958 drawings: http://www.stern.de/panorama/mittwochslotto-lotto-sechser-bringt-nur-40000-euro-1571494.html (in German, last paragraph, you might want to use Google Translate: http://is.gd/g6x5V )

If this happened in the USA there would be a major investigation as someone would be suspected of rigging the game. Weighting the balls by injecting them or some other trick well known here in the States.

There are 3,838,380 possible combinations, so you should see a duplicate around 2,000 drawings. If they do 1 drawing per day, this should happen in about 5 years, so it is not that amazing. A similar situation arises when you ask the students in the class for their birthdays. You don't need 365 students to have a good chance at a duplicate. The chance is quite high with as few as 25 students.

Yeah sure, Satan loves Reversing all and everything. Now we know who really controls the lottery. Dont play it people.
