Question

11. A baseball team is known to win 75% of their games, and the team wins 90% of their home games. 50% of the teamís games are at home.

a. Given the team won their next game, what is the probability that it was a home game?

b. Given the team lost their next game, what is the probability it was a road game?

Answer #1

P(team win) = 75% = 0.75, P(team lost) = 1 - P(team win) = 1 - 0.75 = 0.25

P(team win | home game) = 90% = 0.90

P(Home games) = 50% = 0.50

P(Home game and team win) = P(team win | home games) * P(home games) = 0.90 * .50 = 0.45

P(Road games) = 1 - P(Home games) = 0.50

**a. P(Home game | team win)**

The probability that it was a home game given the team won their
next game is **0.6**

**b. P(Road game | team lost)**

P(Road game and the team lost) = P(team lost | road games) * P(road games) = 0.10*0.50 = 0.05

The baseball World Series is won by the first team to win four
games. Suppose both teams are equally likely to win each game. What
is the probability that the team that wins the first game will win
the series?

The World Series in baseball is won by the first team to win 4
games in a series of 7. Clearly it cannot go longer than 7 games.
Assume the two teams are evenly matched. (a) What is the
probability that the team to win the first game wins the series?
Explain the reasoning behind your computation in words. (b) Suppose
that a team wins the first two games. What is the chance that it
wins the series?

The regular baseball season is 162 games. If a team wins 92
games, it will probably make the playoffs. If the team has a 50%
chance of winning each game, what is the probability that it will
win exactly 92 games? What is the probability that it will win at
least 92 games? Repeat these two calculations assuming the team to
have a 55% chance of winning each game. [You can make some
approximations if you like].

A team play a series of games with win, lose, or draw outcomes.
The transition probabilities between winning, losing, and drawing
are averaged over a long time and treated as independent: Loss Draw
Win Loss 0.3 0.4 0.3 Draw 0.4 0.5 0.1 Win 0.2 0.4 0.4 A. If the
team wins two games in a row, what is the probability that it will
draw its next game? B. On average the team wins 50% of the time,
draws 20% of...

Suppose that the New England Colonials baseball team is equally
likely to win a game as not to win it. If 5 Colonials games are
chosen at random, what is the probability that exactly 3 of those
games are won by the Colonials? Round your response to at least
three decimal places.

One day, a city's baseball team lost their 78th game of the
season and tied the city's major sport record for most consecutive
losing seasons at 16. A losing season occurs when a team loses more
games in a season than it wins. A typical baseball season consists
of 154 games, so for the team to end their streak, they need to
win 77 games in a season. Complete parts a through c below.

There were 2430 Major League Baseball games played in 2009, and
the home team won the game in 53% of the games. If we consider the
games played in 2009 as a sample of all MLB games, test to see if
there is evidence, at the 5% significance level, that the home team
wins more than half (50%) of the games.
a. Write the null and alternative hypotheses
b. Check the Central Limit Theorem
c. Set up your sampling distribution...

A team that wins 4 games out of 7 is the winner. Suppose that
Team S and Team R face each other in the final game and that Team S
has probability 0.55 of winning a single game over Team R .
Find:
The probability that Team S will win the series.

A local soccer team has 6 more games that it will play. If it
wins its game this weekend, then it will play its final 5 games in
the upper bracket of its league, and if it loses, then it will play
its final 5 games in the lower bracket. If it plays in the upper
bracket, then it will independently win each of its games in this
bracket with probability 0.3, and if it plays in the lower bracket,...

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...
