The World Series in baseball continues until either the American League team or the National League team Wins four games. (So they will either play a total of 4, 5, 6, or 7 games.) Let's represent each outcome with a string of A's and N's, so that, for example, if 5 games are played, AANAA represents the outcome Where the American team wins games 1, 2, 4, and 5, and the National League team wins game 3. (a) If the Series consists of exactly 6 games, how many different outcomes are possible? (For example, one outcome is AN NANN. Another is NAANAA.) (b) How many outcomes are possible (including outcomes where either 4, 5, 6, or 7 games are played)? Suppose the National League team is expected to win each game with probability 0.6, independent of other games. (c) What is the probability that exactly 6 games are played and the National League's Team wins the Series
