The envelope paradox (2006)
This seems like nonsense. Here is one reason why: let&#x27;s examine this:<p>&gt; <i>Before you see A, choose a random number R</i><p>This is underspecified. Pick a random number in what range?<p>Suppose we programming in a language which has arbitrary precision integers and floats, and we are given a requirement, &quot;write a function which chooses a random number&quot;. What the heck do we implement?<p>I think this relies on having the <i>same</i> random number generation method as the adversary who prepares the envelope. But if that&#x27;s the case, we can just reason about that directly.<p>If we know that the opponent is, say, using a function that generates a random IEEE 64 bit double, then by looking at the A value, we know the odds that this method will produce a higher or lower value.
