College instructors who adopt this book are (we hope!) twice as likely to continue to use the book the following year as they are to drop it, whereas nonusers are seven times as likely to remain nonusers the following year as they are to adopt this book. (a) Determine the probability that a nonuser will be a user in two years. (b) In the long term, what proportion of college instructors will be users of this book?
