Webb.) The conditional PDF of Y given X is f Y (y x) = 3y² if 0 ≤ y ≤ x ≤ 1 (or 0 ≤ y ≤ 1) or 0 otherwise. c.) The conditional expected value of Y given X is ¾. How we got the answers is in the Explanation part. So, please be guided. WebAug 8, 2014 · Two-boxing dominates one-boxing: in every state, two-boxing yields a better outcome. Yet on Jeffrey's definition of conditional probability, one-boxing has a higher expected utility than two-boxing. There is a high conditional probability of finding $1 million is in the closed box, given that you one-box, so one-boxing has a high expected utility.
