That is only partially correct.
Zero probability events are not impossible.
Yes they are.
Lets take my last example:
Scaff
If I have a box of 100 coloured balls, made up as follows:
20 Black
20 Blue
20 Red
20 Yellow
20 Green
Now I take all of them and put them in a bag and we look at the probability of drawing a red ball out of the bag. Its 20 (number of red balls in the bag) in 100 (total number of balls in the bag), which can be reduced to 1 in 5. This would be commonly stated as being a 0.2 or 20% probability.
Now what is the probability of drawing a Pink ball out of the bag?
Its zero, no Pink balls exist in the data set (the balls contained within the bag) and as such zero probability exists that one can be drawn. It is an impossibility.
What you are claiming is that even with no pink balls in the data set one can still be drawn out, which is quite frankly ridiculous.
Now this does lead onto the crux of the issue; does this mean that Pink balls don't exist? No of course it doesn't, I could have a pink ball on the desk and just have not placed it into the bag, if I were to do so and a probability of drawing a Pink ball now exists.
Here's a little challenge for you, can you now calculate the probability of drawing each of the different coloured balls now that I've added the Pink one.
The key factor here however is two fold:
- Zero probability events are just that, they will not occur
- Probability can't be used to prove soemthing exists
Now it doesn't matter how much you want the above two points to not be true, they are and will remain so.
They are non-probable, or strictly possible.
Possibility transcends the scale of probability and is infinite in scope.
All probabilities are possibilities, but not vice versa.
Probability is of limited scale, since as you say is confined to known events.
Many things are not probable.
There is nothing that is not possible.
Depending on your perspective, the possibility of something maybe impractical or unlikely to the point of inconceivability, wherein it seems impossible, but nonetheless, however remote it may be, it is still possible.
Hence the saying, "anything is possible".
All of the above = nonsense
Case in point, until the early nineteen hundreds man had never flew by independantly sustained or powered mechanical means.
Therefore prior, it could not be a probability.
Needless to say, it was certainly possible.
Once again you fail to actual demonstrate that you understand probability at all and are simply trying to use it as an abstract concept.
Each attempt at powered flight has a probability of success depending on a very large range of factors; the four key ones however were :
- Structural Integrity (the vehicle has to stay together)
- Aerodynamics (it has to generate lift)
- Speed (it has to be able to reach a speed to generate enough lift)
- Weather (affects aerodynamics, engine efficency, etc)
Now if an attempt is carried out in a vehicle that doesn't generate lift (as in the wing design is wrong) then the probability of it achieving powered flight is zero. It will not occur.
In fact if any of the above (and a huge number of other variables) are not reached, then the attempt has a probability of zero.
Its quite clear to anyone that has an understanding of Probability that it is not a tool to validate the existence of anything (and you are the only one claiming, incorrectly, that it is) and you have now repeatedly failed to prove otherwise (and its a zero probability event of you doing otherwise)
Now stop filibustering with this and actually provide the evidence you claim you have and/or actually answer some of the very direct questions you have been ignoring.
