Let p, q, and r be the propositions
p : You get an A on the final exam.
q : You do every exercise in this book.
r : You get an A in this class.
Write these propositions using p, q, and r and logical connectives (including negations).

  1. You get an A in this class, but you do not do every exercise in this book.
  2. You get an A on the final, you do every exercise in this book, and you get an A in this class.
  3. To get an A in this class, it is necessary for you to get an A on the final.
  4. You get an A on the final, but you don’t do every exercise in this book; nevertheless, you get an A in this class.
  5. Getting an A on the final and doing every exercise in this book is sufficient for getting an A in this class.
  6. You will get an A in this class if and only if you either do every exercise in this book or you get an A on the final.
