Consider four nonstandard dice, whose sides are labeled as follows (the 6 sides on each die are equally likely).
A: 4, 4, 4, 4, 0, 0
B: 3, 3, 3, 3, 3, 3
C: 6, 6, 2, 2, 2, 2
D: 5, 5, 5, 1, 1, 1
These four dice are each rolled once. Let A be the result for die A, B be the result for die B, etc.
(a) Find P(A > B), P(B > C), P(C >D), and P(D > A).
(b) Is the event A > B independent of the event B > C? Is the event B > C independent of the event C >D? Explain.

Trump De Drum Ltd (TDT) is a company in aquacultural industry specialised in farming of aquatic organisms. DT is considering opening a new farm in Sandy Bay. This project would involve the purchase of 13 hectares land at a price of $1,000,000 (Note that: The land is not subject to depreciation for accounting and tax purposes). In addition to that, the company will need to purchase eight special equiments which cost $125,000 each. The equipments are expected to be in use for 5 years and after that, they will be scrapped without any residual value. Each year, each of these equipments will incur $5,000 maintenance cost. It is assumed that the farm will first be used at the beginning of the next financial year: 1 July 2021.
Before starting this new operation, TDT will need to redevelop and renovate the warehouse at the farm. This is expected to cost $200,000. Assume that TDT is not able to claim any annual tax deduction for the capital expenditure to the renovation of the building until the business is sold.

Operating variable costs associated with the new business including material costs and labour costs. Estimated material costs per tons in year 1 is $2,000 and this cost will increase by 3.5% every year. The farm will require about 6 workers working for 8 hours a day, 200 days per year. The pay rate is flat at $20/ hour including superannuation. Annual operating fixed costs associated with production (excluding depreciation) are $100,000. Existing administrative costs are $550,000 per annum. As a result of the new operation, these administrative costs will increase by 30%. The company is subject to a tax rate of 30% on its profits.
Meanwhile, TDT Ltd is currently financed by 60% of equity and 40% of debt. Company’s bond is traded at a price of $980. The bond has 10 year term, 8% coupon rate paid semi-annually and face value of $1,000. In addition, company’s equity has a beta of 1.2 while the risk-free rate in the market is 3% and market portfolio return is estimated to be 12%.

that the initial investment could be sold at the end of the five
years for $1 million. Briefly comment on your results and make
appropriate remarks on the assumptions made for these calculations
if necessary.
Estimate the Internal rate of return (IRR) of the project. Briefly

Isabel Briggs Myers was a pioneer in the study of personality types. The personality types are broadly defined according to four main preferences. Do married couples choose similar or different personality types in their mates? The following data give an indication. Similarities and Differences in a Random Sample of 375 Married Couples Number of Similar Preferences Number of Married Couples All four 29
Three 127
Two 111
One 67
None 41
Suppose that a married couple is selected at random. (a) Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common. (For each answer, enter a number. Enter your answers to 2 decimal places.) 0 1 2 3 4
(b) Do the probabilities add up to 1? Why should they? Yes, because they do not cover the entire sample space. No, because they do not cover the entire sample space. Yes, because they cover the entire sample space. No, because they cover the entire sample space.

(a) Make another stemplot of this data by splitting the stems, placing leaves 00 to 44 on the first stem and leaves 55 to 99 on the second stem of the same value.
(b) Create a histogram that uses class intervals that give the same pattern as the stemplot you created with the split stems. It might be a good idea to do this by hand. If you use software, you may have to adjust the settings in order to get a histogram that matches the stemplot exactly.
