Question

If berries are ripe along the trail, hiking is safe if and only if grizzly bears have not been seen in the area. *

r→ q ↔ ¬p

Answer 1

Denote by $r$ the statement "Berries are ripe along the trail". Let also $q$ denotes the statement "Hiking is safe" and $p$ denotes the statement "Grizzly bears have been seen in the area".

Then the statement "If berries are ripe along the trail, hiking is safe if and only if grizzly bears have not been seen in the area." is denoted as $r→ q ↔ ¬p.$
