Anyone with a degree in statistics and probability could identify how Facebook trading will open tomorrow?

The social network’s much ballyhooed offering was in the midst of its second-straight day of declines, dropping as low as $30.98 today. That would have been an 18.5% drop from its IPO of $38.

To be sure, it is only midday Tuesday and Facebook’s shares could rebound.

But for now, the most-traded IPO in history has gotten off to one of the ugliest starts in recent history.
