Free-throw practice At the end of basketball practice, each player on the team must shoot free throws until he makes 10of them. Dwayne is a 70%free-throw shooter. That is, his probability of making any free throw is 0.70. We want to design a simulation to estimate the probability that Dwayne make10 free throws in at most 12shots. Describe how you would use each of the following chance devices to perform one trial of the simulation.

a. Slips of paper

b. Random digits table

c. Random number generator

Short Answer

a. The papers are then placed on a table, numbers facing down. Then jumble the sheets so you can't tell which number is on which table. And choose one of the paper slips. The free throw was made if the number was 1,2,3,4,5,6or 7; otherwise, the free throw was missed.

b. We'll now pick a row from the random digits database. After that, choose the first digits table. After that, choose the first digit. The free throw was made if the digit was between 1and 7(inclusive); otherwise, the free shot was missed.

c. we'll count how many numbers we need till we have ten digits ranging from 1to 7, indicating that 10free shots were made.

Step by step solution

01

Part (a) Step 1 : Given Information

We have to describe how you would use slips of paper device to perform one trial of the simulation.

02

Part (a) Step 2 : Simplification

There is a basketball practice for each player to shoot free throws in the question, and there is a 0,70chance of making any free throw, which equates to around 7out of every 10shots. As,

0.70=70100=710

Now we'll write the numbers 1to 10on separate slips of paper. After that,

1,2,3,4,5,6,7=Make free throw

8,9,10 = Miss free throw
The papers are then placed on a table, numbers facing down. Then jumble the sheets so you can't tell which number is on which table. And choose one of the paper slips. The free throw was made if the number was 1,2,3,4,5,6or 7; otherwise, the free throw was missed.

Now we'll continue until ten free throws have been made, and then we'll count how many trials it took to get ten free throws.
03

Part (b) Step 1 : Given Information

We have to describe how you would use random digit table device to perform one trial of the simulation.

04

Part (b) Step 2 : Simplification

There is a basketball practice for each player to shoot free throws in the question, and there is a 0.70chance of making any free throw, which equates to around 7out of every 10shots. As,
0.70=70100=710
We'll now pick a row from the random digits database. After that, choose the first digits table. After that, choose the first digit. The free throw was made if the digit was between 1and 7(inclusive); otherwise, the free shot was missed. So, we'll keep going until we get ten free throws, then count how many trials it took to get ten free throws.
05

Part (c) Step 1 : Given Information

We have to describe how you would use random number generator device to perform one trial of the simulation.

06

Part (c) Step 2 : Simplification

There is a basketball practice for each player to shoot free throws in the question, and there is a 0.70chance of making any free throw, which equates to around 7out of every 10shots.
As,
0.70=70100=710
Now we'll look at numbers one through ten, as follows:
Make a free throw with1,2,3,4,5,6,7.
Missed free throws 8,9,10
Now, in your Ti83/Ti84calculator, type the following command, which will simulate 30shots as:
randInt(1,10,30), whererandIntis located under PRB in the MATH menu.
As a result, we'll count how many numbers we need till we have ten digits ranging from 1to 7, indicating that 10free shots were made.

Temperature and hatching How is the hatching of water python eggs influenced by the temperature of a snake’s nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: cold, neutral, or hot. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother.

Suppose we select one of the eggs at random.

a. Given that the chosen egg was assigned to hot water, what is the probability that it hatched?

b. If the chosen egg hatched, what is the probability that it was not assigned to hot water?

A total of 25repetitions of the simulation were performed. The number of makes in each set of 10simulated shots was recorded on the dotplot. What is the approximate probability that a 47%shooter makes 5or more shots in 10attempts?

a.5/10

b.3/10

c.12/25

d. 3/25

e.47/100

Superpowers A random sample of 415children from England and the United States who completed a survey in a recent year was selected. Each student’s country of origin was recorded along with which superpower they would most like to have: the ability to fly, ability to freeze time, invisibility, superstrength, or telepathy (ability to read minds). The data are summarized in the two-way table.

Suppose we randomly select one of these students. Define events E: England, T: telepathy,

and S: superstrength.

a. Find P(T|E). Interpret this value in context.

b. Given that the student did not choose superstrength, what’s the probability that this child is from England is ? Write your answer as a probability statement using correct symbols for the events.

Reading the paper In a large business hotel, 40%of guests read the Los Angeles Times. Only read the Wall Street Journal. Five percent of guests read both papers. Suppose we select a hotel guest at random and record which of the two papers the person reads, if either. What’s the probability that the person reads the Los Angeles Times or the Wall Street Journal?

Tall people and basketball players Select an adult at random. Define events T: person is over 6feet tall, and

B: person is a professional basketball player. Rank the following probabilities from smallest to largest. Justify your answer.

P(T)P(B)P(T∣B)P(B∣T)
