A roulette wheel is divided into 38 labeled pockets, 18 of which are red, 18 are black, and 2 are green. Each round, you can place a $1 bet on one specific red or black pocket with odds of 35 : 1. That is, if you are correct you receive $35 in addition to the dollar you bet, and if you are incorrect, you get nothing. Your friend has developed what he describes as a “foolproof system” for winning. It involves him repeatedly betting $1 on red pocket number 7. You try to discourage him, but he is insistent. (a) What are your friend’s expected winnings after one spin of the wheel? What are his expected winnings after 36 spins of the wheel? (b) Despite showing him the outcome of the above calculation, he is unwavering in his opinion, so you decide to at least try to make some money for yourself. You bet your friend $20 that at the end of 36 spins he will have lost money, i.e. have less money than he began with. What are your expected winnings in this bet? What are your friend’s expected winnings after 36 spins taking this side-bet into account as well? (c) Explain what went wrong.

Please show in steps with explanations!

Thanks!

A city is experiencing over-exploitation of its grazing areas. The city council is looking for a consultancy organization that can suggest viable solutions. Your research team is bidding for this job, and you are responsible for the methodology section in the bidding document.

Carefully explain what you would include in the methodology section. Your explanation must include the details of the method (or methods) you choose, the data that need to be collected, the assumptions or restrictions you may want to make, and also the strengths and weaknesses of the method(s).

XML and JAVA

Write a Java program that meets these requirements. It is important you follow these requirements closely.

• Create a NetBeans project named LastnameAssign1. Change Lastname to your last name. For example, my project would be named NicholsonAssign1.

• In the Java file, print a welcome message that includes your full name.

• The program should prompt for an XML filename to write to o The filename entered must end with .xml and have at least one letter before the period. If it does not, print a warning and prompt again. Keep nagging the user until a proper file name is entered.

• Prompt the user for 3 integers.

o The three integers represent red, blue, and green channel values for a color. o Process the numbers according to the instructions below

o Once you have handled the 3 input values, prompt the user again o Keep prompting the user for 3 integers until the user enters the single word DONE

o Reading input should not stop for any reason except for when the user enters DONE.

o The user will not mix DONE and the numbers. The user will either enter 3 integers OR the word DONE

• Once the user is done, open the filename entered in the first step and output the data.

o If no numbers were entered, then do not open the file for writing. Simply print a message that no data was entered.

o When 1 or more colors are entered, write out the XML data for each color. See below for the format.

o Sometimes users may enter integer values that are larger than 255 or less than 0. Values like this will need to be “clipped”, that is, converted to good values. For example, if the user enters 300 for red, then the actual red channel value will be 255. If the user entered -10 for the blue channel, then the actual blue channel value will be 0.

You should follow the sample below and your program should exhibit the same behavior. For full credit, your generated XML files must pass validation with NetBeans Check XML.

GENERAL REQUIREMENTS

All Java-related assignments will have the requirements below. While you may find them limiting, their purpose is to help you adopt good programming habits.

1. You should not have one, ginormous main() function. Your program should be modular, that is, define several (more than 2) meaningful functions in addition to main().

2. All functions should have a comment describing their purpose.

3. You may not use the System.exit() function   
4. You must include a comment at the top of your .java file in this format:

/*******************

John Nicholson

CSCI 3020 Section 04

Fall 2019

Assignment 1
This program does ...

*******************/

You should obviously change the name to your name, the section to your section, and write a real description of the program. If this comment is missing, you will automatically lose 50% of the points on the assignment. Your assignment will not be regraded if you do not put in the correct comment.

Letter # 3: Negative Message
Assignment: You are a recent college graduate and are applying for a number of jobs. Unfortunately, you receive two offers on the same day and need to accept one and decline the other. Write a letter to the hiring manager (see below) explaining your acceptance of another offer, keeping in mind the five goals of delivering bad news, found on page 193. You select the scenario that is most applicable to your current situation.
Preparation: Review Chapter 8: Writing Negative Messages (Especially pgs. 193-195)
Format: Use the modified block letter format for this assignment. Please refer to page 421-423 for an explanation of the block and modified block formats. The example in your book on page 422 is a block format letter while the example on page 423 is modified block letter format. Please note the differences carefully.
There are two main ways to format a negative message letter; directly or indirectly. You can find comparisons of these strategies on pages 193-194. For this exercise, you will be utilizing the direct approach, since you do not need to maintain any formal relationship with the organization you are declining. Follow the organization on pages 195-196 as a guide.
The format of your letter tells the reader a lot about you and your professionalism. Since you do not want to completely cut ties, it is important to leave a lasting respectful impression. Pay particular attention to your letter's margins, line spacing, font type and size, and placement of letter parts such as the return address, date, inside address, salutation, complimentary close, and signature block.
 The information for the job you are declining is: Assistant Manager, Hilton Corporation.  The contact person for this position is: Terrence Walters, Hiring Manager, Hilton Corporation, 555 SW 8th St., Miami, FL 33199.   
Recommended Organization
Introduction/Opening: Begin your letter with the bad news. The indirect approach includes a buffer, however, the direct approach does not. Be sure to remain professional and concise in this section to not sound rude or ungrateful for the opportunity.
Body/Discussion: In the first paragraph of the body include your reasons for the decision, without too much detail about the other position. Having the right balance of ambiguity is respectful to the employer you are declining. Use creativity when developing reasons for taking the other position over theirs. Maybe the schedule was more flexible or the other position better fir your skill set. These are just a few examples to consider when writing this section.   

An instructor who taught two sections of engineering statistics last term, the first with 25 students and the second with 30, decided to assign a term project. After all projects had been turned in, the instructor randomly ordered them before grading. Consider the first 15 graded projects.

(a) What is the probability that exactly 13 of these are from the second section? (Round your answer to four decimal places.)

(b) What is the probability that exactly 9 of these are from the first section? (Round your answer to four decimal places.)

(c) What is the probability that at all 15 of these are from the same section? (Round your answer to six decimal places.)

If you could please explain how to do it out on a calculator that would be much appreciated as the exam will ask us to solve this problem using a TI 84 plus CE.

Riddle begins below:

"Blowing Bubbles," by Sondra Prull

Studying stats just made me tense,

I had to find some sane defense.

Some light and lifting simple play

To float my math anxiety away.

Blowing bubbles lifts me high

Takes my troubles to the sky.

POIK!

They're gone, with all my stress

Bubble therapy is the best.

The label said each time I blew

The average number of bubbles would be at least 22.

I blew and blew and this I found

From 64 blows, they all are round!

But the number of bubbles in 64 blows

Varied widely, this I know.

20 per blow became the mean

They deviated by 6, and not 16.

From counting bubbles, I sure did relax

But now I give to you your task.

Was 22 a reasonable guess?

Find the answer and pass this test!
