The vertices of the graph below showthe courses that are being taken by more than one student, with an edge connecting two vertices if there is a student in both courses. Find a way tocolor the vertices of the graph with only four colors so that no two adjacent vertices have the same color and explain how to use the result to schedulethe final exams.arrow_forward
