Oh no not another free will thread.

Isn't that exactly what happens after a quantum event occurs?  We know the result with absolute certainty, without knowing why or how the result happened?

Isn't it known mathematically though? That works in the same way as logic.

As far as I'm concerned there is no "why"... only how. And the how is shown with the math.

They don't know why or how it happens.  The random aspect is a mystery. 

So much a mystery, that the prevailing theories are 1) It's truly random.  2) That new instances of reality are created for each event, so both result 1 and result 2 happen.
