### Undirected Graph and Stochastic Matrix Computation

**Graph Description:**

Consider the undirected graph below with vertex set \( V = \{ 1, 2, 3, 4, 5, 6, 7 \} \):

- **Vertices:** The graph consists of 7 vertices labeled from 1 to 7.
- **Edges:** The graph has the following edges:
  - Vertex 1 is connected to vertices 2, 5, and 3.
  - Vertex 2 is connected to vertices 1, 4, 5, 6, and 7.
  - Vertex 3 is connected to vertices 1 and 4.
  - Vertex 4 is connected to vertices 2, 3, 5, and 6.
  - Vertex 5 is connected to vertices 1, 2, 4, and 7.
  - Vertex 6 is connected to vertices 2, 4, and 7.
  - Vertex 7 is connected to vertices 2, 5, and 6.

**Graph Visualization:**

The visual representation of the graph is as follows:

```
    1———2———7
     |  / | \ |
     | /  |  \|
     5———6———
     | \  |
     | \  |
     3———4 
```

**Problem Statement:**

Compute the stochastic matrix \( P \) for the random walk on this undirected graph.

### Stochastic Matrix Explanation

To compute the stochastic matrix \( P \) for the random walk on this undirected graph, follow these steps:

1. **Determine the Degree of Each Vertex:**
   - Degree of vertex 1 (d(1)) = 3 (connected to 2, 3, and 5)
   - Degree of vertex 2 (d(2)) = 5 (connected to 1, 4, 5, 6, and 7)
   - Degree of vertex 3 (d(3)) = 2 (connected to 1 and 4)
   - Degree of vertex 4 (d(4)) = 4 (connected to 2, 3, 5, and 6)
   - Degree of vertex 5 (d(5)) = 4 (connected to 1, 2, 4
