View Full Version : Probability of winning 9 straight coinflips
I'm currently on a heater where I have won the last 9 overcard vs pocket pair gambles (me being a 45% favorite going allin preflop). Is there any way to calculate the probability of this happening?
I'm not 100% certain (in fact it is a coin flip lol) but isn't it (1/2)^9?

This is correct if flipping coins.
If a 45% favorite, it is similarly .45^9.

yes, that's correct!. i don't understand the wording. is 45% the favorite? unless there's a big push potential, you'd be an underdog.
but yes, .45^9.... i know 50% to the 9th is 1 in 512. yours would be even longer-shot
I assume you meant your odds of winning were 45% on each hand. The odds of it happening are 1322-1.
The odds of it happening to you are 100%

Small correction to the second statement: there are no such odds that say that you are the exception and that you have no chance of being the 1 in 1322.
on the contrary, the odds are 1:1491.33333333, as long as you take the inverse of the reverse coralation....
Drew Da Donk,
Are you sure??? I always assumed that if there was a chance in a 100 to win (or loose) I could be the one! lol /images/graemlins/smile.gif

I must re evaluate your statement, as the negative impact of the variance of the negative axis recordulates the inverse, you get your answer.... think about it
Drew Da Donk,
Thanks for your clarification. You must be right /images/graemlins/smile.gif
The point I was trying to make is, that often, people will say there is only 1 chance in a million... therefore it must be rigged /images/graemlins/smile.gif And I know that is wrong.
Anyway, enough wine and calvados for the night... time to call it a day...
Sorry for the uncalled for comment, and keep on enjoying /images/graemlins/smile.gif

It's also possible the OP meant he was a 55-45 favorite on each hand. In that case, it was just 1/217 or so that this would happen. /images/graemlins/smile.gif

You missed the point---
It already happened to him---hence, 100%
