consider the directed graph
![**Directed Graph and Outdegree Calculation**
Consider the following directed graph:
- The graph consists of five vertices labeled as \(a\), \(b\), \(c\), \(d\), and \(e\).
- The directed edges are represented by arrows connecting the vertices.
- From \(a\) to \(b\)
- From \(a\) to \(e\)
- From \(b\) to \(c\)
- From \(b\) to \(d\)
- From \(e\) to \(b\)
- From \(e\) to \(d\)
**Outdegree of Each Vertex**
Calculate and give the outdegree for each vertex. The outdegree is the number of edges leaving a vertex.
- \(a:\) [Enter the outdegree of \(a\)]
- \(b:\) [Enter the outdegree of \(b\)]
- \(c:\) [Enter the outdegree of \(c\)]
- \(d:\) [Enter the outdegree of \(d\)]
- \(e:\) [Enter the outdegree of \(e\)]
**Diagram Explanation:**
The diagram is a directed graph with specific connections between vertices, illustrated by arrows. The vertices themselves are represented as dots with labels. The task is to determine the number of edges originating from each vertex.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F40f6d95d-c24b-4013-9814-a24bad0518b8%2F5e73439d-4e4c-459e-b3b2-353ab4685795%2Fqj3czyr_processed.png&w=3840&q=75)
