And his is 2! Since his number is lower than everyone else's, Keltham is guessing that he's probably using the 1-12 scale a different way than others here, but that's fine, everyone just use your scale the way it means something to you.
Now, again without taking others' opinions into account - especially considering that people might be using different real meanings for their scales, so who knows if anybody really disagrees - consider the chance that there will be duck for lunch, AND when Keltham spins this coin, it will fall Abrogail's-face-upward. In other words, both things have to happen, so if the coin lands text-up, it doesn't matter if there's duck for lunch or not, the combined event didn't happen.
Generate new numbers for this combined event, same 1-12 scale from very unlikely to very likely. Please stick to your original opinion and original scale, rather than guessing what others mean by their numbers and updating off those.
Raise your hand when you've got it, then everybody says their numbers.
