Description

What are some ways that you can think of to apply probability theory in business or even in one’s personal life? For example, if you were playing a game of poker with your friends, it would be helpful to know how the probability for winning a hand with a pair of aces in your hand is different than if you were holding a two of clubs and nine of hearts. When investing your money, you might need to choose between an investment that has a 95% chance to earn 3% or one that has a 65% chance to earn 30%. Business owners and managers make numerous decisions throughout the life of the business that are based on the probability of an event happening, consumer tastes changing or remaining the same, a production goal being met on time, and so on.

In this Assignment, you will respond to a set of questions that focus on probability theory, including how the concept informs decision making and can be used by organizations.

Submit your responses to the following prompts.

  • A midsized company recently divided all employees into four divisions. Division 1 makes up 43% of the company, Division 2 makes up 40%, Division 3 makes up 12%, and Division 4 makes up 5%. Choose one employee at random. Find the probability for each of the following statements. (75 words, or 1 paragraph)

    • The employee belongs to either Division 2 or Division 3.
    • The employee does not belong to Division 1 or Division 2.
  • Jasmine Robbins wants to open an independent coffee shop in a town that already has 9 coffee shops: 3 Mocha Moose, 2 Elkhorn Coffee, and 4 Morning JoJo. She is trying to determine the probability of choices that potential customers may make. Here is one of her questions: If a person selects one shop at random to purchase coffee, find the probability that it is either a Mocha Moose or a Morning JoJo. Explain your answer. (75 words, or 1 paragraph)
  • The following chart shows the number of customer complaints from three regions of an organization for two separate years.
    20182017
    Northeast region6,4933,401
    Southeast region7322,513
    Central region3,7061,082
    Find the probability for each question. (75 words, or 1 paragraph)
    • What is the probability that a complaint was from the Southeast region, given it was in 2017?
    • What is the probability that a complaint was from the Central region, given it was in 2018?
    • What is the probability that a given complaint did not occur in 2018 and was not from the Southeast region?
    • What is the probability that two complaints chosen at random were both from the Northeast region?
  • A management consulting team needs a team of four to analyze the operations of a new client. The team should comprise an accountant, a production specialist, a finance specialist, and a management specialist. On its staff, the consulting firm has available six accountants, five production specialists, three finance specialists, and eight management specialists. How many different teams could be formed from the available individuals? (75 words, or 1 paragraph)
  • In a batch of 20 television picture tubes, 5 are known to be defective. What is the probability that a random sample of 5 (without replacement) will result in each of the following? (75 words, or 1 paragraph)
    • Exactly 1 defective
    • No defectives
    • Two or fewer defectives
  • The board of directors for a particular company consists of 10 members, 6 of whom are loyal to the current company president and 4 of whom want to fire the president. Suppose the chair of the board (who is a loyal supporter of the current president) suggests to randomly select 4 other board members to serve on a committee to decide the president’s fate. Find the probability for the first 3 questions and explain your answer for the fourth question. (75–150 words, or 1–2 paragraphs)
    • What is the probability that all 5 committee members will vote to keep the president in place, if no one changes their minds?
    • What is the probability that a majority of the committee will vote to keep the president in place, if no one changes their minds?
    • What is the probability that the vote is 4 to 1 to replace the president, if no one changes their minds?
    • Imagine that you were the president of the company and you hoped to keep your position. Considering the various probabilities, would you consider the chair of the board’s suggestion to be in your favor or not? If the choice was yours, would you allow the suggestion to proceed?
  • Dave has just left an interview with a prospective employer. The hiring manager told Dave that she will tolerate one mistake during his first year but will fire him if he makes two mistakes. Based on Dave’s research and understanding of the job, he estimates that he will have to make five critical decisions during the year, and with his knowledge of the processes, figures that he will have about an 80% chance of making any of those five decisions correctly. Dave does not want to run any more than a 25% chance of being fired. If each of the decisions is independent of the others, should Dave risk taking the job if offered? Explain why or why not.

Explanation & Answer

Hey, hope you're doing well.Here is the assignment :)

BY DAY 7
Submit your responses to the following prompts.

A midsized company recently divided all employees into four divisions. Division 1 makes up 43% of the
company, Division 2 makes up 40%, Division 3 makes up 12%, and Division 4 makes up 5%. Choose one
employee at random. Find the probability for each of the following statements. (75 words, or 1
paragraph)
The employee belongs to Division 1.
If we add up the percentages from each division they all add up to 100%. This means that we can be sure
that all of the Divisions are separate and there is no overlapping between the employees in each
Division. Therefore the probability that the employee chosen at random is from Division 1, since
Division 1 makes up 43% of the company, is 43/100 = 𝟎. 𝟒𝟑.
The employee belongs to either Division 2 or Division 3.
Division 2 makes up 40% of the company, so the probability of the employee belonging to Division 2 is
0.40. Division 3 makes up 12% of the company, so the probability of belonging to Division 3 is 0.12.
Now we want to consider the probability of the employee belonging to either Division 2 or 3. To do this,
we add the probabilities. Therefore, the probability of the employee belonging to either Division 2 or
Division 3 is 0.40 + 0.12 = 𝟎. 𝟓𝟐.
The employee does not belong to Division 1 or Division 2.
The probability of the employee belonging to Division 1 is 0.43 and the probability of the employee of
belonging to Division 2 is 0.40. Therefore the probability of belonging to either Division 1 or 2 is
0.43 + 0.40 = 83. Finally, the probability of the employee NOT belong to Division 1 or 2 is 1 −
0.83 = 𝟎. 𝟏𝟕

Jasmine Robbins wants to open an independent coffee shop in a town that already has 9 coffee shops: 3
Mocha Moose, 2 Elkhorn Coffee, and 4 Morning JoJo. She is trying to determine the probability of
choices that potential customers may make. Here is one of her questions: If a person selects one shop at
random to purchase coffee, find the probability that it is either a Mocha Moose or a Morning JoJo.
Explain your answer. (75 words, or 1 paragraph)
We have a total of 9 coffee shops. There are 3 Mocha Moose, therefore the probability of choosing to
purchase from Mocha Moose is 3/9. There are 4 Morning JoJo, therefore the probability of choosing to
purchase from Morning JoJo is 4/9. Now, the probability of selecting to purchase from either Mocha
Moose OR Morning JoJo is the sum of the two probabilities, which is: 3/9 + 4/9 = 7/9 = 𝟎. �...
