I just need question 2 answered. I will paste the link to the answer for number one that was answered by another chegg tutor.  https://www.chegg.com/homework-help/questions-and-answers/suppose-two-teams-fun-let-s-call-domestic-shorthairs-cache-cows-play-series-games-determin-q46585145?trackid=JideZNSx

Suppose that two teams (for fun, let’s call them the Domestic Shorthairs and Cache Cows) play a series of games to determine a winner. In a best-of-three series, the games end as soon as one team has won two games. In a best-of-five series, the games end as soon as one team has won three games, and so on. Assume that the Domestic Shorthair’s probability of winning any one game is p, where .5 < p < 1. (Notice that this means that the Domestic Shorthairs are the better team.) Also assume that the outcomes are independent from game to game.

We will compare different series configurations/rules on two criteria: the probability that the better team wins the series, and the expected value of the number of games needed to complete the series.

Best-of-Three Series

  1. Determine (exactly) the probability that the Domestic Shorthairs win a best-of-three series, as a function of p. (Show your work. Also note that you solved this for a particular value of p in Quiz 4, so you might want to review that quiz.)


2. Graph this function for values of .5 < p < 1 (include good axis labels), and comment on its behavior. [Hint: As with Investigation 2, you could use Excel or RStudio or Wolfram Alpha to produce the graph.]

Homework Answers

Answer #1

to win a best-of-three series the Domestic Shorthairs need two wins

we know the probability of winning a single game is p

the range of p is 0.5<p<1,where 0.5<p<1

On X axis we will have values of p

On Y axis we will have f(p)  

We can conclude from the graph as the probability of winning a game increases the probability of winning the series increases in a linear manner

A volleyball team is entered in a tournament. Rounds of the tournament are played as best of three; that is, each team will play the opponent in that round until one of the teams has won two games. Suppose that teams are matched up evenly in the first round of the tournament, such that either team has an equal chance to win. For subsequent games, if a team had just won they will be more confident and more likely to...

Markov Chains: In baseball, basketball, tennis, and various other sports, the winner of a tournament is determined by a best of five or best of seven rule; that is, whichever team can win three or, respectively, four games first is the winner of the series. Such tournaments are presumed to be more fair than a single elimination game in determining the better team, since the outcome of any single game has a large element of chance. Suppose that two teams,...
