In a national basketball association, the top free-throw
shooters usually have probability of about 0.95 of making any given
free throw. Complete parts a through c.
a. During a game, one such player shot 11 free throws. Let X
=number of free throws made. What must you assume in order for X to
have a binomial distribution?
b. Specify the values of n and p for the binomial distribution
of X in part a.
c. Find the probability that the player made all 11 free
throws, 10 free throws, and more than 8 free throws.

Expert Solution
a)
Assumption- For X to have a Binomial distribution, all the free
throws should be independent of each other.
In a national basketball association, the top free-throw
shooters usually have probability of about 0.95 of making any given
free throw. During a game, one such player shot 9 free throws. Let
X = number of free throws made.
Kay has an 80% probability of making a free-throw in basketball,
and each free-throw is independent. Kay gets to take 2 free-throws,
and must make both to win the game. What is the probability that
Kay's team will win the game?1. 64%2. 80%3. 88%4. 160% (so 100%)
A basketball player is practicing his free throws. This player's
probability of making a free throw over his career is 0.592. He
will shoot 140 free throws.
a) Define a random variable, and write out the probability mass
function for the number of free throws this player makes on his 140
attempts.
b) What is the probability that this player makes between 60 and
62 free throws, inclusive?
c) What is the expected value and variance of the number of...
A basketball player has a probability of p = 0.78 to hit a free
throw. During a training session he hits 65 free throws. calculate
the probability that the player hits no more than 50 free throws
out of the total 65. (correct to 3 decimal places rounded down)
Please show answer using R commands.
Exercise 3: Bob is a high school basketball player. He is a 60% free throw shooter. That means his probability of making a free throw is 0.60. Use R commands to answer the following questions. (
(a) During the season, what is the probability that Bob makes his third free throw on his sixth shot?
(b) What is the probability that Bob makes his first free throw on his sixth shot?
Jacob is a basketball player who has a 40% probability of
successfully making a free throw
(a) In practice, Jacob keeps shooting free throws until he makes
one in. Then, he stops and runs a lap.
i. What is the probability that he attempts at most 2 free
throws before he has to run a lap?
ii. What is the expected number of free throw attempts Jacob
makes before he has to run a lap?
(b) In a game, Jacob...
When six basketball players are about to have a free-throw
competition, they often draw names out of a hat to randomly select
the order in which they shoot. What is the probability that they
shoot free throws in alphabetical order? Assume each player has a
different name.
P(shoot free throws in alphabetical
order)=?
(Type an integer or a simplified fraction.)
To test his free throw skills, a basketball player shoots 200
free throw shots in a row. He makes 171 of them. Based on this,
what is the probability he will make his first free throw in his
next game? What method of calculating probability did you use to
calculate this?
A basketball player was an 84% free throw shooter.
a. At the moment you turn the game on he is 5 of 7 shooting from
the free-throw line. What is the probability that he made 5 of his
first 7 shots?
b. What is the probability that he made his 5th shot on his 7th
attempt?
c. What is the probability that he made his first shot on his third
attempt?
It is known that a certain basketball player will successfully
make a free throw 87.4% of the time. Suppose that the basketball
player attempts to make 14 free throws. What is the probability
that the basketball player will make at least 11 free throws?
Let XX be the random variable which denotes the number of free
throws that are made by the basketball player. Find the expected
value and standard deviation of the random variable.
