Textbook Question

Chapter 5.5, Problem 34E

For its Music 360 survey, Nielsen Co. asked teenagers and adults how each group has listened to music in the past 12 months. Nearly two-thirds of U.S. teenagers under the age of 18 say they use Google Inc.’s video-sharing site to listen to music and 35% of the teenagers said they use Pandora Media Inc.’s custom online radio service (The Wall Street Journal, August 14, 2012). Suppose 10 teenagers are selected randomly to be interviewed about how they listen to music.

a. Is randomly selecting 10 teenagers and asking whether or not they use Pandora Media Inc.’s online service a binomial experiment?
b. What is the probability that none of the 10 teenagers use Pandora Media Inc.’s online radio service?
c. What is the probability that 4 of the 10 teenagers use Pandora Media Inc.’s online radio service?
d. What is the probability that at least 2 of the 10 teenagers use Pandora Media Inc.’s online radio service?
