**Question 2B:** Consider the graph with the following vertices and edges:

**Vertices (V):** \(\{a, b, c, d, e, f\}\)

**Edges (E):** \(\{\{a, b\}, \{a, c\}, \{a, d\}, \{a, f\}, \{b, e\}, \{b, f\}, \{c, d\}, \{d, e\}, \{d, f\}\}\)

#### Graph Description

The image displays a graph with six vertices labeled \(a, b, c, d, e,\) and \(f\). The edges are drawn between these vertices as follows:

- Vertex \(a\) is connected to \(b, c, d,\) and \(f\).
- Vertex \(b\) is connected to \(a, e,\) and \(f\).
- Vertex \(c\) is connected to \(a\) and \(d\).
- Vertex \(d\) is connected to \(a, c, e,\) and \(f\).
- Vertex \(e\) is connected to \(b\) and \(d\).
- Vertex \(f\) is connected to \(a, b,\) and \(d\).

#### Questions

1. **What is the degree of vertex f?**

   \( \boxed{} \)

2. **What is the total degree of the graph?**

   \( \boxed{} \)

The degree of a vertex is the number of edges incident to it. The total degree of the graph is the sum of the degrees of all vertices.
