3. Project period = 6 years, initial investment cost = 40,000 (KRW 10,000), asset disposal amount after 6 years = 10,000 (KRW 10,000) Expected annual salary = 9,000 (10,000 won), interest rate = 12%

1) Analyze whether the above investments are worth investing in, and how much more profit can you get each year if you don't invest? Suggest whether to build or invest. 2) Among the above conditions, there is a 90% probability that the asset disposal amount will be 10,000 won (10,000 won) after 6 years, and a 10% probability that the asset will be 0 won. Then, analyze whether it is worth investing in, and if you do not invest, how much more profit will you have to generate each year to invest? suggest whether
