That is, is it possible to travel along the edges and trace each edge exactly one time. It turns out that it is possible. One way to do this is to trace the (・」e) edges along the boundary, and then trace the star on the inside. In such a manner one travels along each of the ten edges exactly one time. green state credit union clive

WebEuler’s Path Theorem. (a) If a graph has other than two vertices of odd degree, then it cannot have an Euler path. (b) If a graph is connected and has exactly two vertices of odd degree, then it has at least one Euler path. Every Euler path has to start at one of the vertices of odd degree and end at the other.

So we get a sum of $ {n\choose i}\cdot b_i$
