In Excel,
=BINOMDIST(0,600,1/221,FALSE) gives a result of 0.065802786

(220/221)^600 works too.

thanks both of you, but is it .06 percent or 6 percent (the running count is at 790 now btw)

Hey now, that's a pretty good trick, I'm going to use that one.

(220/221)^600=.065803 is ~6.58%, or odds of 14.2:1 against
(220/221)^794=.027299 is ~2.73% or odds of 35.6:1 against
Spreadsheets are handy. The windows calculator works ok too.

ok so i got them again on hand 881, so does that mean the chances of that happening are (1-((220/221)^(881-795)=67.7%)=32.3%?
I got them again in hand 911, though they were called and sucked out on by some moron with 93s. Dont play at bugsys club

I don't understand that expression.

So 3 times in 911 hands? If you want to understand this you may want to read up on the binomial probability distribution. The calculation is easy in Excel:
=binomdist(3,1/221,911,true) gives .409492, i.e. a 40.9% probability of getting AA 3x or fewer in 911 hands
=binomdist(3,1/221,911,false) gives .189411, i.e. an 18.9% probability of getting AA exactly 3x in 911 hands
The most likely number of times you would get AA in 911 hands is 4, and that will happen 19.5% of the time.

You've got this wrong. Even if you never learn to calculate probabilities, you should understand this.
