To find the empirical probability distribution, we need to divide the frequency of each outcome by the total number of trials. In this case, the total number of subscribers is 85.

Service A: 20/85 = 0.235
Service B: 15/85 = 0.176
Service C: 10/85 = 0.118
Service D: 25/85 = 0.294
Service E: 15/85 = 0.176

The best choice is B because it correctly shows the probabilities for each service adding up to 1.
