Who would win in a fight? Polar bear vs Wolverine.

My dumb friend keeps saying that a wolverine would beat a polar bear and “jump on its back and cut its throat” and he seems to think wolverines are faster even though a quick search says otherwise and the only recorded incident of a wolverine killing a bear was at a zoo, where both animals are out of it’s natural habitat. I also doubt a wolverine could jump high enough to get on the bears back. Can someone please settle this stupid ass debate who is more qualified.
