The role of probability in solving the Monty Hall problem
RE: The role of probability in solving the Monty Hall problem
(March 14, 2016 at 10:49 am)Whateverist the White Wrote: Yes, but that is structurally that is part of the problem.  There is no alternate version of the problem in which Monte's behavior is indeterminate.

Imagine you've never watched the show before, and you appear on stage. You can't know whether he will: intentionally pick the goat, intentionally pick the prize, or pick randomly. With incomplete information you don't know what the best course of action for the probability of your success is - it depends on how Monty plays the game.

(March 15, 2016 at 12:36 am)Jenny A Wrote: Sort of. The probability is based on knowing he will always reveal a door you didn't choose. Otherwise he might only reveal another door if you have already chosen the prize.  But, if he must reveal a door, his intentions are irrelivant.  If he reveals a goat, your best bet is to switch.  If he revealed the car, but didn't let you chose it, there's no option to consider.

Incorrect, I already proved it. If he intentionally picks the car, but has opened a goat that means you must have selected the door with the car, and switching in that case will guarantee you loose. His intentions are the only reason there's a benefit to switching.

The WIN/Gallup End of Year Survey 2013 found the US was perceived to be the greatest threat to world peace by a huge margin, with 24% of respondents fearful of the US followed by: 8% for Pakistan, and 6% for China. This was followed by 5% each for: Afghanistan, Iran, Israel, North Korea. -LINK


"That's disgusting. There were clean athletes out there that have had their whole careers ruined by people like Lance Armstrong who just bended thoughts to fit their circumstances. He didn't look up cheating because he wanted to stop, he wanted to justify what he was doing and to keep that continuing on." - Nicole Cooke
