 In this video we provide the solution to question number one for practice exam number one for math 1030 In which case we're asked what is the degree of the vertex F in the graph illustrated to the right? So if you look at vertex F I'm just gonna draw a little circle around it because the degree of a vertex is the number of edges that are connected to it Loops are counted twice if there were any and so if you draw a circle around the Vertex you can see how many edges are in that circle you see there's four edges one two three and four So that means the degree of the vertex is four the correct answer is in fact E
