MeatEtr Posted September 14, 2009 Share Posted September 14, 2009 Ok, I'll spare the details and get right to it. 8 separate rolls all fall into the 1-19 range out of 100. What are the odds of that? Anybody know of any number crunching sites out there? Where all you gotta do is plug in the numbers and it spits out the results for you. Since I don't know how to use the calculator for this. 0 Quote Link to comment Share on other sites More sharing options...
JonS Posted September 14, 2009 Share Posted September 14, 2009 *very* roughly: .2 * .2 * .2 * .2 * .2 * .2 * .2 * .2 = ? (alternately 0.2^8 = ?) 0 Quote Link to comment Share on other sites More sharing options...
Sergei Posted September 14, 2009 Share Posted September 14, 2009 Isn't that just 0.19^8? ie. 0,0000016983563041 or 1.7 out of million. edit: JonS got there faster. But my answer is 0.01^8 more accurate. 0 Quote Link to comment Share on other sites More sharing options...
MeatEtr Posted September 15, 2009 Author Share Posted September 15, 2009 Nice, and in less than 20 mins from when I posted. Although 1.7 million is much higher than I thought it would be. But then again I was pretty much clueless and haven't done this stuff in well over a decade. Thank you! 0 Quote Link to comment Share on other sites More sharing options...
dieseltaylor Posted September 15, 2009 Share Posted September 15, 2009 Also seems wrong. 0 Quote Link to comment Share on other sites More sharing options...
dieseltaylor Posted September 15, 2009 Share Posted September 15, 2009 It has to be remembered that the desired outcome can occur the first time you try it, and the tenth turn. That might imply that it is now unlikely to happen for the next 3.4 million throws. But that in itself is also unlikely. * I would of course check the die. : ) * However in another universe someone is vainly trying to roll under 20 [insert spooky music] 0 Quote Link to comment Share on other sites More sharing options...
Stalins Organ Posted September 15, 2009 Share Posted September 15, 2009 the answer is...it depends. Were they all in sequence? Were there ONLY 8 rolls, or were there more that were not reported? How many other rolls have ever been made using the same system? 0 Quote Link to comment Share on other sites More sharing options...

Michael Emrys Posted September 16, 2009 Share Posted September 16, 2009 Well yes, but likely things happen more often.:eek: Well now, let's think about that a moment. The reason so many unlikely things happen all the time is that so vastly many more things that we can conceive of are unlikely. If only a relatively few things are likely, then by number they may not be popping off quite as often. On the other hand, this only holds if likely things are finite in number. If both turn out to be infinite, than the question is meaningless. If only the unlikely things are infinite, then the answer is trivial. Whether either or both can be demonstrated as infinite is an exercise left to the student. Michael 0 Quote Link to comment Share on other sites More sharing options...
Erik Springelkamp Posted September 16, 2009 Share Posted September 16, 2009 All events are equally unlikely, but there can be a lot of possible events that yield the same result effectively. 0 Quote Link to comment Share on other sites More sharing options...

I'd argue that likely events are more common than unlikely events. Therefore, if both unlikely and unlikely events are infinite in number, the infinity of likely events is larger than the infinity of unlikely events. It turns out that we have a taxonomy of infinities - aleph null is smaller than aleph one, is smaller than aleph two,... 0 Quote Link to comment Share on other sites More sharing options...

Stalins Organ Posted September 17, 2009 Share Posted September 17, 2009 "million to one chances happen nine times out of ten" paraphrase Douglas Adams or sumone similar Terry Pratchett, discworld series - I forget which book - I think it might be the one where the librarian becomes an Orang Utan....oook! from some wiki or other: Traditionally, one has to say "it's a million-to-one chance, but it might just work!" to invoke this rule. It also has to be exactly a million to one - none of this fiddly "995,351 to 1" business, or whatever other number you might end up with. So while the list of things that people have accomplished with million to one chances is quite impressive, the list of things they have failed to accomplish with odds a few percentage points off in either direction is probably a lot longer and involves a lot more fatalities. 0 Quote Link to comment Share on other sites More sharing options...
