Question
p : The temperature is above 89◦
q : We finished studying.
r : We go to the beach.
Write each symbolic statement in words
a. ¬r ∨ (p ∧ q)
b. ¬p −→ (q ∨ ¬r)
c. (q −→ p) ←→ r
Expert Solution
Step 1
(a) ¬p : The temperature is below 89◦
q : We finished studying.
¬r : We do not go to the beach.
(p ∧ q) = (q ∧ p) = We finished studying but the temperature is above 89◦.
¬r ∨ (p ∧ q)= Either we do not go to the beach or we finished studying but the temperature is above 89◦.
