The compound proposition is, "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." where: p:Grizzly bears have been seen in the area. qiking is safe on the trail. r:Berries are ripe along the trail. I wrote my answer as [itex](\neg r \wedge \neg p)\rightarrow q[/itex] But the answer is (q→(¬r∧¬p))∧¬((¬r∧¬p)→q) I honestly don't see this as being the answer. Please help.
