Yes, indeed. That was my initial stance - and it took a lot of shifting
- but I'm now reluctantly accepting that the switchers are right. In the unlikely event that I was a contestant, I would certainly have believed that there was no benefit prior to the thorough airing given to the subject in this thread.
Indeed, and its understandable since on the surface it seems like a simple probability based problem, whereas its actually a probability and information theory based problem - where the injection of a small bit of extra information skews the odds.
There's a pschological trick too, in that only those that switch don;t just their own previous judgment, as only those that think they made the wrong choice will choose to switch. Leaving you will an oppd stat that the more single minded person or teh purpose that believs they arte always rioght won't switch.
It's a 1/3 chance if you stick with your original choice - you started at
1/3 and all that has happened is a 100% certainty that a losing door will be opened [1]. If you want to make it 50-50 toss a coin to decide which of the final doors to open.
[1] And it's not random which door is opened by the host unless you chose the winning door (giving him a choice of two to open).
hich is the winner, thus the odds are now 0.5 for each door. Thus it makes no difference whether one switches doors or not. Statistical probability fi gures are nothing more than reflections of the data they're based on, and o pening one door changes the available data. Missing that point is where so many are going wrong.
ammed into it - the output is merely a reflection of the views of the progr ammer.
t establish it to be true, everyone makes mistakes. It seems to be a popula r myth that high IQ and specialist subject knowledge immunise people from t hat.
