partition

Prove or disprove: every transitive relation on a set X with more 2 points is reflexive

1) 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 connectives (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 hiking 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.
