I'm not sure it's that simple. let's imagine the first envelope contained between 1 andand 1000 dollars, the second double the first. if you open your envelope and it contains a whole number of dollars between 1 and 1000, then you should swap, id take "250 or 750" over 500.

Only if each value is equally likely. If you see $1,000 but figure the envelope-filler is a lot more likely to have been willing to put $1,500 in than $3,000 then you should stick.

But the problem is explicitly about swapping before opening any envelope.
