• Question 3

Small edit made to what Cain and Zoey said.

  • Question 7

Gene’s statement “we–as in the five of us–should assign a probability equal to 0.5 that each of us is obsessed with Japanese culture”–what he’s saying is that they* should assign a probability of 0.5 to Lena’s being obsessed, 0.5 to Dave’s being obsessed, and so on. (*You can take the “they” collectively–so there’s only one assignment of probabilities–or individually, as in each of them should make that assignment of probability; the answer is the same either way.)
