To see three players involved in a pot to hit a set on flop? I've seen this happen twice already. What are also the odds of me losing with 66 when flop comes 676, turn 7 and other to have 77? I've seen this happen once already.

Is there such thing as a "bad luck" if I continue experiencing bad beats over a long period that are way off the chart compared to the odds percentage?

Final example:

10% to happen something over 100 times means it should happen 10 times on average but when I track my hands history that 10% ends up happening 25-40%. Is it safe to conclude that the software is fixed after big sampling of data where the odds are way off? This also isn't sufficient evidence to bring certain software operators to court?

Depends on how many bots are involved

The odds of you losing with 66 against 77 on a 6767x board? 100% in a regular no limit hold'em game. How often do you think you should win with 6666x against 7777x?

Kopogero, because of your past postings here on 2+2 (and only because of your past postings), I am closing this thread. Beginners Questions is not the area to try to float a Pokers Is Rigged trial balloon.

For the actual math question you asked, you might look in (use the search function, not start a new thread) General Gambling>Probability.

If you want to talk about your bad beats, maybe try Poker News>BBV.

If you want to talk about Pokers Is Rigged....there is a specific thread in Internet Poker>Internet Poker just for that discussion.
