If the class contains 35 people, 12 have brown hair, 11 are blondes, 8 have black hair, and the rest are redheads, what is the probability of randomly selecting a redhead and a blonde on two random selections (of one each).

Given the above distribution:

A. how many permutations of redheads are there ?

B. How many combinations of redheads taken two at a time ?

3. An urn contains 12 red balls and 8 green balls. Six balls are drawn randomly with replacement

a. Find the probability of drawing exactly two red balls?

b. Find the probability of drawing at least one green ball?

c. Find the probability of drawing exactly two green balls when the drawings are done without replacement?

1. The Soda class has two fields: a String for the name and a double for the price.

2. The Soda class has two constructors. The first is a parameterized constructor that takes a String and a double to be assigned to the fields of the class. The second is a copy constructor that takes a Soda object and assigns the name and price of that object to the newly constructed Soda object.

3. The Soda class has two getters: one to return the name and one to return the price.

4. The VendingMachine has one field for a Soda. This can initially reference a null object by assigning null to the field.

5. The VendingMachine has one constructor that takes a Soda. Remember to assign a new Soda to the Soda field securely.

6. The addSoda method of the VendingMachine class takes a Soda. Check if the field of the class references a null object (you can use the equals operator to check what the variable references). If the field references a null object, assign the new Soda to the Soda field securely and return true. If the field does not reference a null object, just return false.

7. The removeSoda method of the VendingMachine class takes no arguments. Check if the field of the class does not reference a null object (you can use the equals operator to check what the variable references). If the field does not reference a null object, assign null to the Soda field and return true. If the field references a null object, just return false. 8. In the VendingMachineDemo, change the name and price for the Soda being added to the VendingMachine to any other name and price of your choosing.

Consider the following:

–       You need a $300,000 financing package.

–       $150,000 at 9%, 30 Years

–       $100,000 at 8%, 20 Years

–       $50,000 at 7% 10 Years

1. What is the monthly payment for each part of the financing package?
2. What is the IRR on the $300,000 borrowed?

Does anybody know how to solve these two questions with details?

Please answer the following:

Loan Amortization

Your company is planning to borrow $1.5 million on a 7-year, 8%, annual payment, fully amortized term loan. What fraction of the payment made at the end of the second year will represent repayment of principal? Round your answer to two decimal places.

Thank you!
