<｜begin▁of▁sentence｜>### Instruction:
As a genealogist, you have been researching a family tree with a total of 300 individuals. You are interested in exploring the relationships between a subset of 20 individuals within this family tree. In order to analyze the communication dynamics within this subset, you can use the ForestFireSampler method to sample a subgraph representing the 20 individuals. Once this subgraph is generated, you would like to compute the communicability between all pairs of individuals to understand their interaction patterns.
### Response:
import networkx as nx
from littleballoffur import ForestFireSampler

G = nx.gnp_random_graph(n=300, p=0.1)

sampler = ForestFireSampler(20, p=0.3, seed=123)

sampler_G = sampler.sample(G)

result = nx.communicability(sampler_G)

print(result)
<|EOT|>
