Chapter 4, Problem 9PP
Your sports league uses the following lottery system to select draft picks for the four worst teams in the league:
■ The last place team gets 20 balls in an urn.
■ The second-to-last place team gets 10 balls in the urn.
The third-to-last place team gets 6 balls in the urn.
■ The fourth-to-last place team gets 4 balls in the um.
To determine the first pick in the draft a ball is selected at random. The team owning that ball gets the first pick. The ball is then put back in the urn. To determine the second pick in the draft a ball is selected at random. If the ball belongs to the team that got the first pick then it is put back in and the process repeats until a ball is selected that does not belong to the first pick. To determine subsequent picks in the draft the process repeats until a ball is selected that belongs to a team that has not already been chosen.
Write a function that takes as input which of the four teams have already been granted picks, simulates selecting a ball from the um according to the lottery rules, and returns the team that belongs to the selected ball. You get to choose how to design your function to perform these actions. Write a main function that outputs the draft order (e g., a possible order is: second-to-last picks 1, last place picks 2, third-to-last picks 3, and fourth-to-last picks 4). If you change the random seed then the order should differ if you run the program multiple times.
For a slightly harder version of the problem, allow the user to input the names of the four teams. The program should then output the team names in the draft order.

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90.
Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.
Ex: If the input is:
90
the output is:
The 90 is primary, going east/west.
Ex: If the input is:
290
the output is:
The 290 is auxiliary, serving the 90, going east/west.
Ex: If the input is:
0
or any number not between 1 and 999, the output is:
0 is not a valid interstate highway number.

After painting the white cells of the board, you want to place the maximum number of dominoes on it, according to the following rules: each domino covers two adjacent cells; each cell is covered by at most one domino; if a domino is placed horizontally (it covers two adjacent cells in one of the rows), it should cover only red cells; if a domino is placed vertically (it covers two adjacent cells in one of the columns), it should cover only blue cells. Let the value of the board be the maximum number of dominoes you can place. Calculate the sum of values of the board over all 2w possible ways to paint it.

- Q2 The Powerball Lottery 15 Points The Powerball lottery is based on a random drawing of six balls from two machines. One machine contains 69 white balls (labeled 1 through 69) and the other machine contains 26 red balls (labeled 1 through 26). To determine the winning numbers, the gamemaster draws five white balls from the first machine and one red ball (the "Powerball") from the second machine (assume all outcomes are equally likely). A player in the Powerball lottery picks five different numbers between 1 and 69 (inclusive) and a sixth number between 1 and 26 (inclusive), which may duplicate one of the first five numbers. For each of the following questions, you should write your answer as an expression. Do not give the final numeric value. For example, you should write C(4, 2)/24) instead of 0.375.arrow_forwardWhen you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forwardGreenLawn a local lawn care company has different pricing policies for its customers. GreenLawn sends out monthly invoices and will give discounts if payments are made within 5 days. The discounting policy is as follow: If the amount of the monthly bill is greater than $300, subtract 4 percent from the invoice; if the amount is between $300 and $100, subtract a 2-percent discount; if the amount is less than $100, do not apply any discount. All bills made via the web automatically receive an extra 3-percent discount. Develop a decision for GreenLawn discounting decisions.

The game continues until the game is either won by landing on the red space or lost when the piece moves off either end of the board. Step 1: Place a game piece on a space that is not red and set a counter to 0. Step 2: If the game piece is on a yellow space, move the game piece 3 positions to the left and go to step 3. Otherwise, if the game piece is on a black space, move the game piece 1 position to the left and go to step 3.
