Question 5: Counting Trees Consider the following simple graph with 9 vertices and 12 edges: Assume that all vertical edges have the weight (length) I, and all horizontal edges have the How many different minimum spanning trees does this graph have? Why? (Here, we consider two trees to be different if they include different vertices or edges from the original graph, even if they are isomorphic.)
