 In this video, we provide the solution to question number one for practice exam number two for math 1030 For which case we are given a Digraph right here, and we'll ask what is the in degree of the vertex F in the degree illustrated here So we look for in the vertex F right here The in degree is the number of arrows that are coming into the vertex there We see there's three arrowheads coming in while there isn't an edge leaving that would be part of the out degree So for this vertex here the in degree is three because there are three edges coming into it
