Given the e-reader data presented in Exercise 52.
a) If a randomly selected U.S. adult has an e-reader, what is the probability that he or she hasn't read an e-book in the past year?
b) Is it more or less likely that a randomly selected U.S. adult who does not own an e-reader would have read no books in the past year?
Exercise 52
Pewlnternet reported in January of 2014 that 32% of U.S. adults own at least one e-reader, and that 28% of U.S. adults read at least one e-book in the previous year (and thus, presumably, owned an e-reader). Overall, 76% of U.S. adults read at least one book (electronic or otherwise) in the previous year, (pewinternet.org/Reports/2014/E-Reading-Update/A-Snapshot-of-Reading-in-America-in-2013/Whos-reading-and-how-a-demographic-portrait.aspx).
