Three friends (A, B, and C) will participate in a round-robin tournament in which each one plays both of the others. Suppose that P(A beats B) = 0.8 P(A beats C) = 0.6 P(B beats C) = 0.4 and that the outcomes of the three matches are independent of one another. (a) What is the probability that A wins both her matches and that B beats C? (b) What is the probability that A wins both her matches? (C) What...
Three friends (A, B, and C) will participate in a round-robin tournament in which each one plays both of the others.

Four universities-1, 2, 3, and 4-are participating in a holiday basketball tournament. In the first round, 1 will play 2 and 3 will play 4. Then the two winners will play for the championship, and the two losers will also play. One possible outcome can be denoted by 1324 (1 beats 2 and 3 beats 4 in first-round games, and then 1 beats 3 and 2 beats 4). (Enter your answers in set notation. Enter EMPTY or for the empty...
Suppose four teams, numbered one through four, play a single-elimination tournament, consisting of three games. Two teams play each game and one of them wins; ties do not occur. The tournament bracket is as follows: teams one and another team play each other in the first game and the remaining two teams play each other in the second game; the winner of the first game plays the winner of the second game in the third game. Define a set ΩΩ...
PROBABILITY QUESTION William Gates is about to play a three-game chess match with Steve Jobs, and wants to nd the strategy that maximizes his winning chances. Each game ends with either a win by one of the players, or a draw. If the score is tied at the end of the two games, the match goes into sudden-death mode, and the players continue to play until the rst time one of them wins a game (and the match). William has...

Problem 2 - Bayesian Inference Nisqually, Inc. sells books A,B,C on line. Each customer buys 0 or 1 copy of each title. a. Mrs. Independence Day, the company's data mining expert, makes the assumptions that: i) a customer decides to buy a book independently of what other books (s)he buys and independently of other customers. ii) all customers buy according to the same joint probability distribution PABC = PAPeP. with PA(1)0.6, PB(1) 0.3, Pc1) 0.4. For example, the probability that...
Two players Anvitha (A) and Buhlebenkosi (B) are playing a game. At each round, A wins with probability p ∈ (0, 1) and loses with probability 1 − p. The game ends if one player has won two more rounds than the other. (a) Compute the probability that A wins the game eventually. (b) Compute the mean total number of rounds played when the game ends. (c) Compute the variance of the total number of rounds played.
Question 3 (15 pts). A gambler plays a game in which a fair 6-sided die will be rolled. He is allowed to bet on two sets of outcomes: A (1,2,3) and B (2,4,5,6). If he bets on A then he wins $1 if one of the numbers in A is rolled and otherwise he loses $1 -let X be the amount won by betting on A (so P(X-1)-P(X1)If he bets on B then he wins $0.50 if a number in...
