Question
Spectrum provides cable television and internet service to millions of customers. Suppose that the management of Spectrum subjectively assesses a probability distribution for the number of new subscribers next year in the state of New York as follows.
f(x)
100,000 0.05
200,000 0.20
300,000 0.25
400,000 0.35
500,000 0.10
600,000 0.05
(a) Is this probability distribution valid? Explain.
This probability distribution ---Select--- valid because ---Select--- | for x = 100,000, 200,000, 300,000, 400,000, 500,000, 600,000. Also, f(x)
(b) What is the probability Spectrum will obtain more than 400,000 new subscribers?
(c) What is the probability Spectrum will obtain fewer than 200,000 new subscribers?
