If organic alone attracts X clicks per day, and PPC alone attracts Y clicks per day, then having both in place can attract significantly more than just X+Y. In some cases, it can be as much as 20% more.

I see this on one of my sites. I am organic #8 and PPC #1. While running the PPC campaign, I seem to get more click-throughs from the organic results than when I'm not running the PPC campaign.

I'm guessing that it's either because the the PPC gives more validity to the organic results or that by the time the searcher gets down to the #8 position, he/she remembers seeing my site already and it seems like a familiar domain to them. Maybe a combo of both.
