Question

Determine the truth value of each compound statement when p is false, q is false, and r is true.  You must show how you arrived at your answer for each question.

      (∼p→r)↔(p∨∼q)(∼p→r)↔(p∨∼q)
      ∼[p→(q∧r)]∼[p→(q∧r)]
      ∼[(∼p→r)↔(p∨∼q)]∼[(∼p→r)↔(p∨∼q)]
      (∼p↔r)∧(∼q↔r)(∼p↔r)∧(∼q↔r)
      (q∧∼p)↔∼r
