PB, you teach math, correct? I weep for our youth
Seriously, you are including an option in your math that cannot be realized. The "fake seer, hoops is a wolf" is not an option as I would have scanned villager in that case. Since he is saying I scanned wolf there are only two options.
You can argue that those options are weighted equally - each has an equal 1/6 chance of coming to Darth Vilus. So that would be 50/50.
Or you can argue that there although there is a 50/50 shot of DV getting seer or fake seer as a night action, the chances of scanning a wolf are not equal in a game with more villagers than wolves.
Either way, the odds are certainly not above 50%. I'll argue this one as a math question until I'm blue in the face in the postgame thread if people want to return to the topic when I'm no longer considered an interested party.
