Quote:AhighIt's probably a no-go then because I really only want free bets.

It's not that I am scared of losing, just that I already take free bets with the casino.

In other words, just betting odds over and over and over is effectively the same way to profit from rolling fewer sevens, and I already have a way to do that, and yet I don't actually take odds that often.

We can hold off until there's a better understanding that we are in agreement for the terms, but it sounds like you're thinking I am willing to say I have a 50/50 chance to roll 15% or fewer sevens.

What I'm saying is I would be willing to bet a very large sum of money that I can roll less than 16.67% sevens, and I'll pay a little bit more if I lose that you have to pay if I win.

In general, the reason I am not willing to do anything besides betting I can do better than random is because I already have those bets available here in Vegas since I'm a local, and I don't have much incentive to bet that bet except to take an unnecessary risk that I don't perform as well as I have performed in the past.

I hope it all makes sense. If I come across as sounding less than confident that I can continue to roll 15% sevens, then that's okay, because I'm _not_ confident it will continue!

Okay, I'm starting to understand the disconnect between you and SOOPOO now. So for any bet, you really want the over-under to be the exact (or close to exact) 1/6 number, and for your winning conditions to be under that number of sevens. Is that correct? The reason that I (or anyone) would be less inclined to take that bet is that it is far more likely to happen randomly, of course! I understand you are willing to give up more on your side of the action to compensate. We may yet be able to compromise, given that additional variable.

But let me make clarify something: ideally, the bet would not be a 50/50 proposition for you (i.e. a "free bet"). Ideally we would calibrate it such that you would have a > 50% chance of winning given your influence. I suggested the 15% number since that's what you cited from your past roll data, but that's not set in stone. 15.5% would still be a bias, as would even 16% (I'm not sure what bias is required to beat the house edge, I just sold my 2 dice control books). I'm not trying to waste your time, I promise. I'm trying to test a claim of dice bias. Depending on where we set the line, it could be under the exact 1/6 amount, and still give you a >50% chance of winning assuming some tiny amount of bias.

Say you have a shooter who claims 16% sevens (a very small bias). In a sample of 1008 throws, set the over-under at 164.5 sevens. The shooter (again, assuming the bias to be true), would have a 61.24% chance of hitting the under (164 or fewer sevens). The challenger (again, assuming no bias) would have a 61.30% chance of hitting the over (165 or more sevens). That's about the best you can get as far as giving each party a similar perceived probability of winning a straight bet.

To get the percentages higher, you either need more claimed bias or a longer trial. Here are a few more examples

For the same shooter with a 16% claimed 7 percentage but a 2016 throw trial, set the over-under at 329.5. This gives the shooter a 66.54% chance and the challenger a 64.9% chance. Still pretty good.

Instead, go back to the 1008 trial but take a shooter with 15.5% claimed 7s. Now move the over-under down to 162.5. Harder to line it up exactly now, but this gives the challenger a 67.63% shot, and the shooter a 70.94% shot. Move it to 161.5 and they nearly flip, giving the challenger a 70.63% shot, and the shooter a 67.93% shot.

Anyway, just brainstorming. People who are way better at stats than me, please poke holes in my methodology :)

Careful Buzz..... Choose your words carefully! I'l bet you cannot BEAT me (not tie me) in a one roll contest for who can roll the most boxcars......

Quote:AhighI rolled boxcars back-to-back three times in a row two days ago at Fiesta.

If PaigowDan was there, he would have back-roomed you.

LibreOffice works just as well in Windows and Mac OSX. I prefer it over its proprietary counterparts.Quote:AcesAndEightsOkay, fooling around in LibreOffice Calc (i.e. Excel for Linux nerds :p)

Quote:MakingBookIf PaigowDan was there, he would have back-roomed you.

The first boxcar, I had $6 coming. The next one I had $25 coming. The next one I had $50 coming.

I ended up making $25 on the entire roll, but those boxcars didn't help.

It's not like I am a horn better!!!
