In 2017 the Pew Research Center asked young adults aged 18 to 29 about their media habits. When asked, “What is the primary way you watch television?” 61% said online streaming service, 31% said cable/satellite subscription, and 5% said digital antenna. Suppose the Pew Research Center polled another sample of 2500 young adults from this age group and the percentages were the same as those in 2017.

a. How many would say online streaming services?

b. How many would say cable/satellite subscription?

c. How many would say cable/satellite subscription or digital antenna?

d. Are the responses “online streaming service,” “cable/satellite subscription,” and “digital antenna” mutually exclusive? Why or why not?
