If there are five players in the pot and one of them has AA, normally he is about a 40% favourite to have the best hand at the river.

So, if the opponents call at least as they have a chance to beat AA the probability to loose three times in a row with AA is about 20%.

So, you lost with AA three times in a row. Will you fold that hand the next time?

Btw, I think it does not make much sense to ask for the probability of an event once it has happened. Every combination of hands that is dealt on a ten player table has a very low probability before the cards are dealt. I don't understand why people are asking all these questions like: "How likely is it to get a straigt, a flush, trips, two pair, and a straight in a row?" What will they do with the answer?
