Hello. I will be needing some assistance in this probability question as I find it hard to understand the chapter. Hope you can provide solutions to this question.

Question 2

a) In a regional city, two lawn companies fertilise lawns during the summer. Company A has 72% of the market. Thirty per cent of the lawns fertilised by Company A could be rated as very healthy one month after the service. Company B has the other 28% of the market. Twenty per cent of the lawns fertilised by Company B could be rated as very healthy one month after the service. A lawn that has been fertilised by one of these companies within the last month is selected randomly and is rated as very healthy.

i) What is the revised probability that Company A fertilised the lawn?

ii) What is the corresponding probability that Company B fertilised the lawn?

b) Of 250 employees of a company, a total of 130 are full-time employees. The remain-der are part-time employees. There are 150 males working for this company, 85 of whom are full-time employees. What is the probability that an employee chosen at random:

i) is a part-time employee?

ii) is female and a full-time employee?

iii) is a full-time employee, given that the employee is female?

iv) is a female, given that the employee is full-time?

v) Are the events employee chosen at random is female” and employee chosen at random is full-time” statistically independent?

c) Let P (A[B) = 0:9, P (A) = 0:5 and P (B j A) = 0:4. Calculate P (B) and P (A j B). Are A and B independent? Are A and B disjoint? Justify your answers.

d) Let P (A) = 0:2, P (A [ B) = 0:6, and suppose the events A and B are independent. Calculate P (B).

e) Let P (A) = 0:6, P (A j B) = 0:6 and P (A[B) = 0:8. Calculate P (B) and P (AB). Are A and B independent? Justify your answer.

f) A toy manufacturer buys pre-assembled robotic arms from three different suppliers 50% of the total order comes from Supplier 1, 30% of the total order comes from Supplier 2, and the remaining 20% from Supplier 3. Past data shows that the quality control standards of the three suppliers are different. Two percent of the arms produced by Supplier 1 are defective, while Suppliers 2 and 3 produce defective arms at the rates of 3% and 4% respectively.

Let Si be the event that a given arm comes from Supplier i, i = 1; 2; 3 and let D be the event that a given arm is defective.

i) Draw a tree diagram that models this situation.

ii) What proportion of the arms in the manufacturer’s inventory are non-defective?

iii) If an arm is found to be defective, what is the probability that it came from Supplier 1? Give your answer to 4 decimal places.

Hello!  Can you help me to solve the tasks:

1. In Europe the airlines and railway sectors are competing for the travel needs of the increasingly mobile and massive consumer market. TravelWithUs, a leading airline company is looking to create a new joint venture with FromHereToThere, Inc. a dominant player in the rapid transit railway sector that will provide a huge opportunity to create value through cost reductions in the excessive competition between the two sectors. This joint venture will also be able to provide new travel options to an increasingly demanding customer, combining air and travel routes, to minimize the time taken to travel between various destinations. The new joint venture will have an asset beta equal to 80% the sum of the asset beta of the airline and railway businesses. The joint venture would require a $20 billion investment and would generate after tax free cash flows of about $2.75 billion starting the following year (t = 1) and will grow at the rate of inflation of 3% for the foreseeable future. The joint venture would be financed by a $10 billion issuance of new stock each by TravelWithUs., Inc. and HereToThere, Inc. that will give each company a 50% ownership in the joint venture.TravelWithUs., Inc. has a market value of equity of $50 billion and an industry average debt to equity ratio of 0.60. On the other hand, HereToThere, Inc. has a market value of equity of $25.00 billion and an industry average debt to equity ratio of 0.50. The airline business has an average beta of equity of 2.50, while the average equity beta in the railway business is 1.75. The average returns on debt in the airline and railway industries are 8.00% and 6.75%, respectively. The risk free rate is 2.50% and the expected market risk premium (the difference between the market return and the risk free rate) is 4.00% for the foreseeable future. Assume that the tax rate is 34%, the interest payments on debt are tax deductible and the tax shield on debt is as risky as the assets of a business. What is the beta of assets in the airline business?2. Cable and mobile phone companies are competing with each other for the delivery of content and services to the massive consumer market. The management of Channel Company, Inc., a cable company, believes that creating a new joint venture with Horizon Mobile, Inc., a mobile company, will provide a huge opportunity to create value through synergies in R&D and investments required in distribution systems and markets. The new joint venture will have an asset beta equal to the average of the asset betas of the cable and mobile businesses. The joint venture would require a $2 billion investment and would generate after tax free cash flows of about $175 million per year, starting the following year and continuing into the foreseeable future. The joint venture would be financed by a $1 billion issuance of new stock each by Channel Company, Inc. and Horizon Mobile, Inc., implying a 50:50 ownership in the joint venture by each company.Both the cable and mobile phone sectors are inherently oligopolistic in nature, and both Channel Company, Inc. and Horizon Mobile, Inc. are the only public companies in their respective businesses. There are private companies as well, but no reliable data is available on them. You will therefore be forced to use the data on Channel Company, Inc. and Horizon Mobile, Inc. to conduct all your analysis. Channel Company, Inc., has a market value of equity of $25 billion and a debt to equity ratio of 0.50. On the other hand, Horizon Mobile, Inc. has a market value of equity of $12.50 billion and a debt to equity ratio of 0.25. The equity of Channel Company, Inc. has a beta of 1.75, while the equity beta of Horizon Mobile, Inc. is 0.50. Information on the debt structure of both firms is available due to a recent issuances of corporate debt by both companies, and the returns on debt of Channel Company, Inc. and Horizon Mobile, Inc. are 3.75% and 3.00%, respectively. The risk free rate is 2.50% and the expected market risk premium (the difference between the market return and the risk free rate) is 5.00% for the foreseeable future. Assume that the tax rate is 34%, the interest payments on debt are tax deductible and the tax shield on debt is as risky as the assets of a business. What is the return on equity to the stockholders of Horizon Mobile, Inc. prior to forming the joint venture? What is the beta of assets in the cable business? What is the beta of assets in the mobile phone business? What is the return on assets of the joint venture?

hello,

I was wondering if I could have some help with this problem; there is a list of properties on the natural numbers that the problem asks us to reference and use at our own discretion. However, I’m not entirely sure which properties I should use to prove the following by induction, after having shown the base case. I’m having most trouble showing the inductive case, i.e. the n+1 case.

Let f : N → N be a function. Suppose that f(n)< f(n+1) for all n∈N. Prove that f(n)≥n for all n∈N.

Thank you for your help

All the best

Hello! Im doing some practice problems for an upcoming exam and would appreciate the help!

Why are okazaki fragments required? In other words, why cant all DNA polymerase activity be continuos? Choose all that are correct

a) because DNA polymerase can only add nucleotides to an open 3″-OH group

b)Because the two daughter DNA strands must be made at the same time, to ensure two complete daughter strands are made before mitosis proceeds

c) because DNA replication is bidirectional and both directions must be completed at the same time

d) because DNA polymerase acts as a dimer, adding nucleotides to both strands at the same time
