Re: Odd Escape
Solace, you've got it spot on. Your 33% never changes, but the other door "takes on" the odds from the one that is eliminated, becoming 67%. It's a hard one to grasp, but you got it.
Another way to look at it: Imagine 1,000 doors, one that is correct and 999 that are wrong. You pick one randomly. The gaurd eliminates 998 others. Which do you think is more likely the right one? The one you chose randomly or the one the gaurd left?
I've seen this riddle argued on another forum for several pages, but there is no denying the answer....I was very surprised someone got it so quickly. Goes to show you that this forum has some amazingly intelligent people.
How about this one:
Option A) Play the same set of lottery numbers every week for 52 weeks.
Option B) Play 52 different sets of lottery numbers in one week.
Of course your odds of winning are pretty slim either way, but is one better than the other?
