Let p, q, and r be the propositions p: Grizzly bears have been seen in the area. q: Hiking is safe on the trail. r: Berries are ripe along the trail. Write these propositions using p, q, and r and logical con- nectives (including negations). a) Berries are ripe along the trail, but grizzly bears have not been seen in the area. b) Grizzly bears have not been seen in the area and hik- ing on the trail is safe, but berries are ripe along the trail. c) If berries are ripe along the trail, hiking is safe if and only if grizzly bears have not been seen in the area.

17. Let p, q, and r be the propositions
p: Grizzly bears have been seen in the area.
q: Hiking is safe on the trail.
r: Berries are ripe along the trail.
Write these propositions using p, q, and r and logical con-
nectives (including negations).
a) Berries are ripe along the trail, but grizzly bears have
not been seen in the area.
b) Grizzly bears have not been seen in the area and hik-
ing on the trail is safe, but berries are ripe along the
trail.
c) If berries are ripe along the trail, hiking is safe if and
only if grizzly bears have not been seen in the area.
d) It is not safe to hike on the trail, but grizzly bears have
not been seen in the area and the berries along the trail
are ripe.
e) For hiking on the trail to be safe, it is necessary but
not sufficient that berries not be ripe along the trail
and for grizzly bears not to have been seen in the area.
