Forgive me, but this makes no sense to me.

The probabilities ought to be additive.

That is, if his chance of winning a single 180-person MTT is 1/180, he chances of winning 1 of 2 180-person MTTs ought to be 2/180. And so forth. So his probability of winning 1 180 person tournament given 90 tournaments ought to be exactly 90/180 or 50%. Please explain how I am wrong.

Sherman

PS - FWIW, I know what you were doing by using his current data, I am just pointing out that unless he is a losing player (which he probably isn't) or is trying to lose, his probability of winning a single 180 tournament is surely better than 1 out of 200+.

Not correct.

Each tournament is an independent event. Just because you didn't win 179 in a row doesn't mean you're guaranteed to win #180.

As with any other grouping of independent events you have to calculate the risk of not winning one specific tournament:

NW(1) = (180 - 1)/180 = 179/180 = 0.9944444 ....

From there you can calculate the risk of not winning any of X tournaments:

NW(X) = NW(1) raised to the power X = NW(1) * ... * NW(1) (that reads: NW(1) multiplied with itself X times).

This gives us the chance of winning (at least) one out of X tournaments:

CW = 1 - NW(X)

We're looking for the number of (random outcome) 180/$4.40 to play to have exactly 50% chance of winning one:

X = log(0.5) / log(NW(1)) = 124.4

So to have 50% chance of winning (at least) one tournament in a completely random universe (which doesn't seem too far off when it comes to $4.40 buy-ins) you have to play a little more than 124 of them.

if my math teacher would have told me that math could help me in poker, I would have actually paid attention.

This is suggesting that I'm approximately 50% to win one if I play 124 in a row? That sounds about right.

It's right if you really suck...somehow I doubt you do.

IMO, you ought to be able to win 1 in 90-150 on average.

LOL - If you're going to try to get the betting line to shift, you should be a bit more subtle than this... [img]/images/graemlins/smile.gif[/img]

He's already wussed out even though everybody has pretty much proved what the odds are... I'd still love to get action at 2:1 instead of GIVING 7:1 for god sakes
