<｜begin▁of▁sentence｜>### Instruction:
As a financial planner, suppose a client has a diversified investment portfolio containing 500 stocks and they are interested in analyzing the interconnectedness of these stocks to assess the risk exposure. The client wants to use a simulation approach to sample a subset of 200 stocks and determine if the subset forms a connected network. How can the RandomEdgeSampler be used to sample a subgraph from the stock network and assess its connectivity?
### Response:
import networkx as nx
from littleballoffur import RandomEdgeSampler

G = nx.gnp_random_graph(n=500, p=0.3)

sampler = RandomEdgeSampler(200)

sampler_G = sampler.sample(G)

result = nx.is_connected(sampler_G)

print(result)
