Question

Time Warner Cable provides television and Internet service to millions of customers. Sup-pose that the management of Time Warner Cable subjectively assesses a probability dis-tribution for the number of new subscribers next year in the state of New York as follows. x f(x) 100,000 .10 200,000 .20 300,000 .25 400,000 .30 500,000 .10 600,000 .05a. Is this probability distribution valid

    Answer: yes, it is valid

    Step-by-step explanation:

    Given the following probability distribution :

    X ________f(x)

    100,000___ .10

    200,000__ .20

    300,000 __ .25

    400,000 __ .30

    500,000 ___.10

    600,000 ___.05

    To examine the validity of the distribution :

    Each individual observation or point must have probability value in within the range (0 < p ≤ 1)

    Where p = probability value.

    The sum of the individual probabilities must add up to 0

    (0.1 + 0.2 + 0.25 + 0.3 + 0.1 + 0.05)

    = 1

    Since the two consitions are meet, then, the probability distribution is valid
