Dear anh An Hai,

How can knowing what's in one envelope matter? We are not talking quantum
mechanics here.

I still maintain, by both common sense and my previously posted
calculation, that whether you swap or not the prob of getting the `good' 
envelope is 0.5. And the only reason for swapping is to satisfy one's
curiosity.
