5. One year, the As play the Bs in the World Series, a seven-game series of baseball games. The World Series winner is the team that wins at least four games.1 Suppose that all games

are independent and for each game, the probability that the As win is p (which is the same for each game.) We dont know the exact value of p, but its estimated that in professional baseball, the better team wins between 50% and 70% of games. (a) Suppose p-0.5. Whats the probability that the As win the World Series? b) Suppose p- 0.6. Whats the probability that the As win the World Series? (c) Suppose p 0.7. Whats the probability that the As win the World Series?

    Suppose that you’re watching the World Series. At the beginning of the Series, you believe that the Cubs are a better team than the Indians…. (Sorry, I must pause here. As an Indians’ fan, it hurts to write that.) Anyways, you believe that the probability that the Cubs will beat the Indians in a single game is at least 0.50. You decide to reject this hypothesis if the Cubs fail to win more than 2 games in the World Series....

    A and B play a series of games. Each game is independently won by A with probability p and by B with probability 1−p. They stop when the total number of wins of one of the players is two greater than that of the other player. The player with the grater number of total wins is declared the winner of the series. Find the probability that a total of 4 games are played. Please explain as much as possible.
