Google places and organic results

It very much depends on the type of mixed search results. Let me give you a simple example. If you search for "hotels las vegas", you would notice that the first results are not Google Places. Furthermore, you could notice that the information provided for every single google place is not just "Company Name", "Address", "Phone Number", "Web Page" and "Review Count", but also short description, coming from the site. In this case the "click distribution" would be very different from my next example's one.

If you search for "restaurants las vegas", you would see the Google Places listed as usual, but only below them - the organic results. However, even if you have the tiniest screen and the smallest resolution, you could still see all the Google Place Pages, so it makes it very difficult to predict the "click distribution" as theoretically all of them would have the highest chances to be clicked on. In my opinion, in this case the choice of the potential customer would go to the "most shiny one", or the one with the best rating and most reviews, or with the most appealing name, which in the majority of the cases is not the rank 1 Google Place. Therefore, the answer to your question varies greatly from case to case.
