Use Djikstra Shortest path algorithm between friend A and friend B with each edge cost as 1 .
The result would give you the degree of connection between them.

Normally you can run a Breadth First Search, but in a large network like Facebook you should probably employ some optimisations. Heuristics work great, e.g. people from the same country/city are more likely to lead you faster to the solution.
