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.

A) r ⋀ ~q

B)p⋀q⋀r

C)r--->p

D)p⋀~q⋀ r ( i guess here nevertheless  means "and')

E) (p⋀q)-->r

F)r<-->(q⋁p)

Determine whether each of these conditional statements is true or false. If 1 + 1 = 2, then 2 + 2 = 5. If 1 + 1 = 3, then 2 + 2 = 4. If 1 + 1 = 3, then 2 + 2 = 5. If monkeys can fly, then 1 + 1 = 3.

Determine whether these biconditionals are true or false. 2 + 2 = 4 if and only if 1 + 1 = 2. 1 + 1 = 2 if and only if 2 + 3 = 4. 1 + 1 = 3 if and only if monkeys can fly. 0 > 1 if and only if 2 > 1
