The math seems to show that it is 48.6% that the cards will be next to each other and over 70% that the cards will be within one card of each other. Here is the video and a discussion of the subject: http://headinside.blogspot.com/2012/11/m......dds.html

Any help appreciated. Thanks I think the way I learned it when I was a kid was that given a value and a suit, the probability is very high, over 80%, that you would find a pair of adjacent cards with the value next to the suit. That, at least, is a very old idea. Click here to get Gerald Deutsch's Perverse Magic: The First Sixteen Years All proceeds to Open Heart Magic charity.

In the Friendly Cards, the spec shuffles the cards and the top and bottom cards are looked at. S/he then shuffles again. The magi asks only for the values of the cards, and lo, they are next to each other in the deck. I can verify this citation because in August of 1963, I took out John Mullohand's Book of Magic from my local library. Evidently, I never returned it, because it is sitting on my shelf some 50 years later.
