V ={Red, Yellow, Green}, where each node represents a color state of a traffic light system. E = {(Red, Yellow), (Yellow, Green), (Green, Red), (Red, Green), (Red, Yellow)}, where the edges represent transitions from one traffic light state to another. (a)  Is it a directed graph or undirected graph? (b)  Which of the transitions (edges) do not make sense in practice? For example, does a yellow light follow a red light in traffic? (c)  Modify the set of edges (E) and show the correct traffic light transitions in a corrected graph.
