question about sitting on 20 at the blackjack table,and there are only two possible outcomes
Flawed. Each of those is a chance. 4/50 for an ace and 1-4/50 for bust, 1/1 holding pat, dealing only yourself, with a fresh deck of course.
3 seperate chances, you decide which to take.

Thankyou! Refer back to definition of chance above.
To arrive at 51%, 25%, 99%, etc "probabilities", statistical references, interconf records, common matchups and other measurements would be used to speculate an outcome. This would have nothing to do with "chance".

nonsense and really bad probability theory
Again I say, I didn't write probability terms and definitions. Sorry if you don't like them.

Tennessee has no QB and no offensive line. No Eric Berry. It better be 100 % LSU wins this game.

I said I was giving up, but I can't help myself.
This is not the argument. One can use any number of methods to arrive at a probability of winning a game. There is no way to know who is right or wrong, because as repeated ad nauseam the games will only be played once. All we can do is make educated guesses and see what happens.
But it doesn't matter how accurate one's predictions are to convert individual game win likelihoods into a predicted final win-loss record because the two are one in the same. If I say LSU will finish 9-3, I could just as well say they have a 75% chance of winning each individual game. This is exactly the same as a basketball player who is a 75% free throw shooter. Out of every 12 free throws, on average he makes 9 of them. In other words, typically he scores 0.75 points for each free throw attempted. If the guy just got divorced or something and I think he will be off his game, I could either say I think his FT% will drop to 50% this game, or I could say if he takes 12 FT's, he will only make 6 of them. Either way, it's the same thing. For every shot he takes, I will give him half a point. I may be right, I may be wrong... it's all speculation. All I'm trying to say is you can convert a series of win probabilities into a probable win-loss record (or made-missed free throws, or whatever).
Now let's try the blackjack example. You deal yourself a couple of 10s. That leaves 50 cards, with only the 4 aces giving you 21. In this scenario standing at 20 isn't an option because it's akin to forfeiting a football game. You have to take the hit, resulting in either a win or a loss. Well, 4/50 gives you an 8% (ie. .08 probability) chance of winning. Now give yourself a hit 12 times (not adding them all together, just take each individual hit and see if it's an ace), reshuffling in between. Add together .08 + .08 + etc etc 12 times (or, you know, just multiply) gives you .96, just less than 1. So of those 12 hits (ie. football games) you will probably win once. Of course, you may not win any, or you may win all of them. I'm sticking with my guess of 1 though. Now, if I wanted to predict that you would win 6 out of those 12 hits, I would have to load the deck with aces. In fact, of the 50 remaining cards I would have to stick 25 aces in there to make my prediction probable. As you can see, this changes your probability of a win to 25/50 = .50 = 50%. Putting any other number of aces in the deck just wouldn't make sense. So here comes what I think is your leap of faith: if I load 2 decks, 1 with 30 aces (out of 50 total cards) and one with 20 aces (out of 50 total cards), which corresponds to 60% and 40% wins for you, and deal you 6 hits from each deck, I would still expect you to win 6 of the 12 hits. .60 + .60 + .60 + .60 + .60 + .60 + .40 + .40 + .40 + .40 + .40 + .40 = 6. Think about it... I might as well just shuffle the 2 decks together, which would put 50 aces in a 100 card deck, giving you a .5 probability of winning each hit. The predicted win-loss record is directly related to the probability of winning each individual game. Saying anything else just doesn't make sense.
Now, I don't know if it's the fact that you can convert between those 2 different ways of saying the same thing that has you confused, or if it's the math when varying probabilities are involved. Please tell us exactly what it is about the whole thing that you don't believe or comprehend.

wtf r u talkin bout? I want to play there. Dealer hits to 17, soft or hard depending on house rule and players can stand pat where they please where I've played.

True this, but a game of "chance" involes none of what you speak. That would be 1 of 2.
This is where a point spread comes in and makes it a game of chance, sort of. Handcapping takes an event and makes it as close as possible to a game of "chance"(even money at least), so that the bookie just skims the vigor, or price of doing buisness.

Good point, and frequency probability would support that except for the few attempts. Would you feel confident about a player making 9 of his first 12 going 75% the rest of the season? The 9/12 75% free throw shooter has at least made 12 attempts at some very, very similar hoops. This year's football teams have never played, yet we think we can come up with some mathematical percentage of success, then compile that into a season record? It's just a frickin guess.

Sorry, I missed the no pat part. But in short, no. That would involve two inequal probabilities that would disqualify the term chance, by classical definition.

Correct ,60%= 3/5, 6/10 etc. Check back 10 or 15 posts and it's quoted verbatim. I only repeated it.
I still say as in previous post, it's ok to say I think, have a hunch, gotta good feeling on a game, but there's very vague, unexact measures to try and put percentage points on.
Just where did these numbers come from? To actually numerically quantify each advantage teams have over each other is exhaustive and still very short of exact.

If you are comparing blackjack to a football game, when talking about odds of winning, yes you have to take the hit. Otherwise you're comparing apples to oranges.

Why do you insist that a "chance" means 2:1 odds? A 1 in a million shot is still a game of chance.

This is by far the smartest thing you've said in this thread. You are right, it's all just a huge guess, but a series of guesses on % chance of winning 12 individual games is the same thing as guessing a final record. These two have to be in sync, otherwise you are contradicting yourself. You can't think the odds of winning the lottery are 1 in a million, and then also think you will win it twice next month. For the same reason, it doesn't make sense to give a team a 51% chance of winning each of 12 games, and then predict a 10-2 record in the same breath.
I'm begging you to please think about this for a while before you post again. Open your mind and try to figure out why I'm correct here. Forget blackjack, forget basketball... in fact forget everything you think you know. Don't get pissed with me because you think I'm insulting you or questioning your intelligence. I'm not the smartest guy around, and I admit that on a daily basis, but I know when I'm right and this is one of those times. In fact there is 0% chance that I am wrong. Ask a statistics professor, or better yet show him this thread so nothing gets lost in translation.

quote:I saw that. But what you quoted was not a definition of the word "chance", but rather a use of the word in the phrase "theory of chance", a term of art used in statistics and some probability study. The essay from which you quoted was expounding on a specific application of LaPlace's mechanics of infinitesimal calculus. That is a methodology for reasoning the probability of past unwitnessed events having actually occurred based upon witnessed events. While that usage of the word "chance" is meaningful in that area of probability studies, it is by no means the only meaning of the word and is not close to the usage employed in this conversation. For more relevant meanings of the word "chance," you can see here.
Check back 10 or 15 posts and it's quoted verbatim. I only repeated it.
If Merriam Webster is too plebeian for you, you can try this:
quote:
Probability is a number representing the likelihood that a particular event will occur by chance.
quote:where "chance" is used to describe a determining factor of probability, which includes intuitive probability where informal criteria (as opposed to true randomness) are applied.
Three definitions of Probability
* A priori: rational analysis as in the examples.
* Relative frequency: if there are many experiments of the same kind, the probability of a favorable event would be
. . .
*Intuitive Probability : An evaluation of the probability based on informal criteria.
In statistics all three definitions are used.
The meaning of "chance" is this discussion is more particularly that expressed in definition 4(a) of the Merriam Webster:
quote:The fact that the science of statistics often manages that notion with the term "probabilities" instead of "chance" does not change the fact that the term "chance" does indeed fit.
the possibility of a particular outcome in an uncertain situation; also : the degree of likelihood of such an outcome <a small chance of success>
However, on a more academic note, I think your initial analysis might still be flawed, because in fact the sample space of a football game is not two outcomes. Even though Texas beating Akron by 40 and Texas beating Akron by 4 are both Texas wins, they are in fact two different outcomes that are simply grouped into the same event (Texas wins). One could suggest that there are infinity outcomes in each event (with the two teams theoretically capable of scoring any two unequal integers), making each as likely as the other to occur randomly. But in fact there are not. There are physical limitations on the amount of scoring that can even theoretically occur (it will always take some time for points to be scored, and the clock will eventually run out). As such, there is a finite number of possible outcomes. And since those physical limitations are inherently both varied and non-random, the outcomes cannot be assumed to be equally distributed between the two events.
Again, that is all irrelevant to the discussion because you used the wrong meaning of the word chance in the first place.
