A simple graph has 6 vertices and 12 edges. Each vertex has degree either 2 or 5. How many vertices have degree 2 and how many have degree 5? Can you draw an example of such graph? Show that in a connected simple graph any two paths of maximum length must intersect (i.e. must have at least one vertex in common).
