I once got rolled up 5's back to back in 7 stud, what're the odds of that?

Somewhat worse than 7-1

What about subscripts? Can you program this forum to accept subscripts?

Doesn't seem to work.

David,

This question isn't that great, but it's probably less disappointing than most of the others. I ordered the book from amazon almost a month ago, and it has been delayed a few times. Do you know anything about this? problems with supply, shipping, whatev?

craziest thing that happened to me is a guy getting kings four straight times in a live game. He got it 3rd time...they changed the deck and he got it again. He literally busted the entire table...at least it broke up aftewards.

You were only off about 7 orders of magnitude. That's not so much, in the grand scheme of things.

Although an accurate estimate, properly it's this:

I'll use the notation (x y) for "x over y", which is x!/((x-y)!*y!), or combinations.

First, you need to be dealt 2 deuces: (4 2) / (52 2). That is, 2 cards out of 4 good cards, out of 52 total.

Second, you need the complement chance of the flop not showing a deuce: 1 - ((48 3) / (50 3)). That is 3 cards out of 48 good cards (50 remaining minus 2 deuces) out of 50 total.

Then you can multiply all this and raise it to the 3rd power for it to happen 3 times in a row.

(4 2) = 4!/2!*2! = 4*3/2 = 6
(52 2) = 52*51/2 = 1326
(48 3) = (48*47*46)/(3*2) = 17296
(50 3) = (50*49*48)/6 = 19600

Gives: (6/1326) * (1 - (17296/19600)) = 0.0045248 * (1-0.88244) = 0.000531935.

That's the probability of it happening once, 3 times it's: 0.000531935^3 = 1.51*10^-10. Or about one in 6,643,900,265. (that's rounded)

1. Have you read the book yet?

2. How do you rate it on a 1-10 scale (rounded to nearest .25 multiple)

3. Will the book prove itself immediately useful for limit or NL hold em?

lol, are you [censored] high? go read the "verizon puts a 71$ beat on someone" thread in BBV, and realize that your level of stupidity is up there with the average verizon service rep.
