Changing the Discussion Settings in LEO The following instructions show how you should set up your discussion settings in LEO. 1. You should click on discussions. 2. Then you want to click on settings. 3. The interface looks like this 4. The next step is to change some settings. Look at this next picture. 5. Did you see what we just changed? Good! 6. Want to know the next step? Here it is! 7. I hope you see that two settings have now been changed. Examine the pictures closely to see what has been changed. It’s important. 8. Clicking save will save these settings. 9. Now, click on any particular discussion, and you will see how the changes change the interface. For example, you could click on student introductions, as the screen capture below indicates: 10. Take a look. Cool, eh?!? 11. And more cool features are shown in the next picture. I hope this helps. This course is concerned with the basic understanding of probability and it's applications. The goal is to learn and you get back what you put in. Briefly state the question and use the Equation Editor to present all equations clearly. Answer any 2 questions. For probability questions, define events as: A: drawing a 10♣ B: drawing a 9♥ P(A&B) = P(A)P(B|A) = ?? Special Exercises (1to 5) 1. What is the probability of drawing at random the 4♥ and the 9♣ from a deck of cards on two successive draws? Use Insert/Insert symbol to get the heart, club, diamond, spade symbol by selecting the drop down menu to the left of Paragraph. Also, click on the drop down menu next to the Black Square icon in the menu of the Editor to change colors of the characters. 2. 18 people were poled and 10 said they have shopped at Wal-Mart and 8 said they have shopped at Target. 4 said they shopped at both. What is the probability that the group shopped at Wal-Mart or Target?. 3. Define independent and mutually exclusive events mathematically by using P(A) & P(B) for events A & B. 4. What is the probability of randomly drawing a 10 or a ♦ from a deck of cards? 5. What are the total possible outcomes of rolling a pair of dice? Note that the pair 3,4 is not the same as the pair 4,3. What is the probability of rolling a 7 with a pair of dice? P(7) = No. of successful outcomes/Total No. of outcomes In questions 1,2,4, begin by clearly defining events A & B as shown below. For example, A: 4♥ and B: 9♣. State P(A)=??, P(B)=?? and then apply the appropriate equations , such as P(A&B) = P(A)P(B|A) or P(AorB) = P(A)+P(B)-P(A&B) Substitute values and compute the answer. I urge you to read the attachments in the Videos-Topics In Stat 230/Probability Rules. I prefer to use P(A&B) or P(AorB) instead of P(A∩B) or P(A∪B). You will see the latter on the final so be sure you know what the "∩" and "U" symbols mean.

COMPLEMENTARY EVENTS & Try It 3.19 in Illowsky Complement_&_Rule.swf The complement of an event A is the event A does not occur. The complement of event A is denoted by Ac and either event A or Ac must occur. Therefore, P(A) + P(Ac) = 1.0 or,
- 4. P(A) = 1.0 - P(Ac) For example, consider tossing a fair coin 10 times. Define event A as; A: Observe at least one head Ac: TTTTTTTTTT (observe no heads, 10 tails are tossed) P(Ac) = (12)10=11024 P(A) = 1.0 − P(Ac) =1−11024=.999 We are fairly sure of observing at least one head in ten tosses. Dependent vs Independent Events Independent Events: Consider tossing two die. What is the probability of throwing a "One" on die #1 and then a "Six" on die # 2? Answer is 1/6 times 1/6 = 1/36. These events are independent of each other and P(A&B) = P(A)P(B). Dependent events: What is the probability of drawing the Queen of Spades and the King of Spades if no card is repaced after the first draw. We apply the rule that P(A&B) = P(A)P(B|A) = P(B)P(A|B). Since A is the queen, P(A) = 1/52 and to then draw the kink, P(B|A) = 1/51, the answer is 1/52 times 1/51. Recall that P(B|A) means the probability that event B occurs given that event A has already occurred. Event B is dependent upon event A occurring. WRTG 293 students, Your first writing assignment will be to rewrite a set of instructions. The scenario for this assignment is described below. ________________________ You have just taken a position as a student worker for the Communications Arts Department at
- 5. Anderson College. You began your job last week. Anderson College has an enrollment of 10,000 students. Among this student population, 20% of the students are international students for whom English is not a native language, 10% of the students are dual-enrollment high school students, 20% of the students are graduate students, and the remaining 50% of the student population consists of a mixture of adult learners and traditional students. Anderson adopted LEO as its learning management system two years ago. Anderson uses LEO for both its online classes and its hybrid classes. Since moving to LEO, Dr. Richard Johnson, Dean of the Undergraduate School at Anderson, and Dr. Lynn Peterson, Dean of the Graduate School at Anderson, have noticed that both students taking classes at Anderson and instructors teaching at Anderson are often not aware of the different settings one can choose to view discussions in LEO. This lack of awareness has caused confusion and frustration as students and faculty members have attempted to navigate through the discussions in their classes. Dr. Johnson and Dr. Peterson tried to address this problem two months ago. At that time, they asked the previous student worker to write instructions on how to change the settings for discussions in LEO for the optimal viewing arrangement. The previous student worker wrote some instructions. However, the worker wrote them very
- 6. unprofessionally and poorly. They cannot be distributed to students in their current form. Moreover, shortly after the student worker finished the instructions, he left his position for another job. As a result, Anderson College now has a set of poorly designed instructions that it cannot send out to students and faculty members. Meanwhile, students and faculty members are still experiencing frustration with the system, and they need a document that guides them through how to adjust their settings in LEO for viewing discussions. Dr. Johnson, who is your immediate supervisor, has now asked you, the new student worker, to rewrite the instructions that the previous student worker wrote. He has asked you to use the same graphics the previous student worker used. He has also suggested that you use arrows to point to sections of the graphics if such arrows can help in understanding specific steps in the instructions. Keep in mind that potentially 10,000 students will be using the instructions, in addition to various faculty members. The instructions should be clear, professional, and well designed. Moreover, you will want to consider the different types of students at Anderson College, including their backgrounds and their varying demographics. Dr. Johnson has given you the following resources to help you
- 7. in this project: • Instructions: Tell Them How to Do It! by David McMurrey • Instructions: How to Write Guides for Busy, Grouchy People • Wikibooks’ Professional and Technical Writing/Instructions Dean Johnson has informed you that your introduction should be very short—no more than one paragraph of about 4-5 sentences. ___________________________ Strategies to Consider for this Assignment: Consider your audience. Your primary audience is the students and faculty members at Anderson College. However, Dean Johnson will be reviewing your document as well. Most likely, department heads will be viewing it also. Therefore, the dean and the department heads can be considered secondary audiences. Length of your instructions: There is no minimum or maximum number of words for this document. You will want to follow the advice given in the three resources that Dean Johnson provided for you as you design the new set of instructions.
- 8. Due Date: Your instructor will notify you of the due date. You will write a first draft, your instructor will comment on the first draft, and you will submit a second draft using the comments as your guide.
