(b) If for every subset A C 2 of size |A| = k, where k is some fixed element in {2, ..., N}, and every outcome w E 2 it is true that P1 (@ | A) = P2 (w | A), then is it necessarily true that P1 (@) = P2 (@) for all w E ? For the following two parts, assume that 2 = \\ (a1, ..., ak) | E,_jaj =n, is the set of configura- tions of n balls into k labeled bins, and let P1 be the probabilities assigned to these configurations by throwing the balls independently one after another into the bins, and let P2 be the probabilities assigned to these configurations by uniformly sampling one of these configurations. (c) Let A be the event that all n balls land in exactly one bin. What are P1 (@ | A) and P2 (@ | A) for any @ E A? How about w E 2 \\ A? Is it true that P1 (@) = P2 (w) for all w E ? (d) For the special case of n = 9 and k = 3, please give two outcomes B and C, so that P1 (B) P2(C)
