I don’t care how you got the numbers, I care that they are incompatible with each other. That’s the point here.
If you calculate the probability that I have blonde hair is 33%, and you calculate the probability that I don’t have blonde hair is 90%, then it doesn’t matter how you calculated those probabilities, one of them has to be wrong. They are incompatible probabilities.
So there is a 50 out of 51 probability (98%) that you picked the blue ball out of bag #1, and therefore a 98% chance that what’s left in that bag are all blue balls.
If there’s a 98% chance that what’s left in the bag are all blue balls, and “all blue balls” necessarily implies 0 red balls, then there must also be a 98% chance that the bag has 0 red balls.
There are 2 bags, each bag started with a 50% chance of being the bag that the ball was pulled from. So it is not right to claim the bag has a 98% chance of containing 0 red balls.
I don’t think that 50 of 51 equates to only a 2% chance of having a red ball in that bag.
So you’re now saying, there’s a 98% chance that the bag contains only blue balls, but there’s NOT a 98% chance that the bag contains 0 red balls? How does that work?
I am sure, it doesn’t work. You cannot produce a data set with these statistical properties, because they are impossible to coexist. The probability of A, and the probability of not(A), cannot add to more than 100% (barring some weird word play or trick question, I suppose, which this is not)
“So there is a 50 out of 51 probability (98%) that you picked the blue ball out of bag #1, and therefore a 98% chance that what’s left in that bag are all blue balls.”
Are you backing away from that position? Do you now think otherwise?
I’m not denying it, I’m saying I don’t know that it is true. I’m not sure that 50 of 51 blue balls in 1 bag means that there is a 98% chance the ball was pulled from that bag, because there was a 50% chance of pulling the ball from either bag at the start. Each bag had a 50% chance of being the bag the first ball was pulled from, even though we knew at the start one of the bags contained 98% of the blue balls.
Okay, well at least the good news is you’re finally grappling with the contradiction, that’s what I’ve been hoping for for the past few pages of this conversation.
The bad news is, of your two contradictory positions, you’re backing away from the one that was right.
I can show that the 98% position is correct, with Bayes theorem, and I’m capable of producing software that you can easily run that will run the experiment, randomised, hundreds of thousands of times and tell you the results.
Last time I offered experimental evidence of this sort, you were uninterested. I don’t know if your attitude towards that has changed by now.
I don’t know what you mean by “my methods”. I’m going to write software that simulates the experiment randomly. Ideally, it’s not “my methods” or “your methods” or anybody’s method, but just a fair recreation of the scenario using software. You’d be free to read and review the code, it would be possibly readable even to a non software dev.
