This is a Quantitative methods assignment but is mostly all basic statistics theoryprobability and numbers as well. Question 3.2 3.3 and 3.4 and question 4 should provide good detail but doesn't have to be that long maybe a couple paragraphs if need be

MGSC 1206 May-June, 2016 Due 02 June, 5pm (130 points) Assignment 3 1. Use shading to show each set in the Venn diagram. A A B B ?? ?? (A?B)?B (a) A?B (4 points) (b) (4 points) 2. Suppose that P(A?B)=0.8, P(A)=0.5P(B'). Determine P(A). (10 points) (1) Assume that A and B are independent (2)Assume that A and B are mutually exclusive. 3. We usually design two versions of the midterm exam paper for the course MGSC 1206. We do not have the cameras in the classrooms. In May, 2016, Version A had the same statements as Version B except for one number in each of Question 1, 2, and 3. (For example, Question 2 of Assignment 3, one version is with P(A)=0.5P(B'), and the other version is with P(A)=2P(B').) John worked on Version A, but the solutions are with the same numbers of Version B. Moreover, John made mistakes in the solving processes of these three questions. As a result, John could have got only several points even if the number differences had been ignored. As we know well, it is possible for a person to make mistakes on reading. According to history data, a person has such a mistake in one question with the probability 5%. Suppose that a person makes the mistake in different questions are independent. (1) What is the probability that John did the exam by himself according to the history data? (2 points) (2) The instructor doubts that John was cheating in the exam. What is the best solution for the instructor? Explain. (20 points) (3) Suppose that the instructor claimed that John cheated. According to the management policy, the cheating behaviour will be recorded into John’s file. John had a chance to talk with the instructor before the instructor reported it to the university. In the meeting, John said that he got a lot of difficulties in life, and had not got much benefit from the behaviour. John negotiated with the instructor,...

3. (2) The instructor doubts that John was cheating in the exam. Now he wants to be sure 
whether his doubt is correct or not and then he wants to take action accordingly. If John 
cheated then there should be some strict action be taken against him so that in future now one 
would like to cheat and if his doubt is merely a doubt and not substantive then John should be 
given proper marks. So instructor want to be sure what is the truth, whether John cheated or 
John did not cheat. 
There may be many ways to decide whether John cheated or not, let us discuss some of them 
here: 
Instructor could give a chance to student that he should accept that he cheated and in that case 
0 mark will be awarded but instructor will not claim in management that John cheated. The 
chances is very high that he had cheated and in such scenario, if instructor claim in 
management that John cheated, then he may be disbar from future exam for a long period. 
There is a great chance that John would accept the truth. 
The person who were sitting next to John should also be asked whether John cheated from his 
paper or not. Even he could be told that if s/he does not reveal the truth, she may also be 
punished. There is great chance that person next to John will tell the truth. 
John may be asked to solve similar question, if he cannot do them in the same level as he did 
in the actual exam, then he must have cheated.
3. (3) There is very less probability that John did his exam by his own, and he could have 
done cheating. But when instructor wants to raise the issue with University, it should not 
merely on the chances. Even probability is very less for his writing the paper on his own, no 
one can exclusively reach the point that he cheated. Punishment must not be given unless 
cheating is proved beyond reasonable doubt.  
Now due to many problems in the life of John,
