The table below lists of five mobile phone companies and indicates whether they have agreements to roam onto each others networks. Draw a graph that represents this information, where each vertex represents a phone company and an edge connects two vertices if the corresponding companies have a roaming agreement. Then use the graph to answer the following question : Which phone company has a roaming agreements with the most carriers? Apple Huawei Phone Company Vivo Yes Yes Apple Huawei No No Vivo Yes Oppo No Samsung Yes Yes No No Yes No Oppo No No Yes - Yes Samsung Yes No X Yes
