Select the best analysis: My cat is normally energetic. But he's been lethargic for the past two days. Just prior, he got his vaccines at the vet's. Since he's normally energetic about 80% of the time, I figure there's a 70% chance his lethargy is due to the vaccines. a) H = he recently got vaccinated; E = he's normally energetic about 80% of the time; P(E/H) = 70%. b) None of the other answers are correct. c) H = He's normally energetic about 80% of the time; E = he recently got vaccinated; P(E/H) = 80% d) H = his lethargy is due to the vaccines; E = he recently got vaccinated; P(E/H) = 70%
