The University of Nottingham
SCHOOL OF MATHEMATICAL SCIENCES
A LEVEL 2 MODULE, SPRING SEMESTER 2019-2020
PROBABILITY MODELS AND METHODS
Suggested time to complete: TWO Hours THIRTY Minutes
Paper set: 18/05/2020 - 10:00
Paper due: 26/05/2020 - 10:00
Answer all SIX questions
Your solutions should be written on white paper using dark ink (not pencil), on a tablet, or
typeset. Do not write close to the margins. Your solutions should include complete
explanations and all intermediate derivations. Your solutions should be based on the material
covered in the module and its prerequisites only. Any notation used should be consistent with
that in the Lecture Notes.
Guidance on the Alternative Assessment Arrangements can be found on the Faculty of Science
Moodle page: https://moodle.nottingham.ac.uk/course/view.php?id=99154#section-2
Submit your answers as a single PDF with each page in the correct orientation, to the
appropriate dropbox on the module’s Moodle page. Use the standard naming
convention for your document: [StudentID]_[ModuleCode].pdf. Please check the
box indicated on Moodle to confirm that you have read and understood the statement
on academic integrity: https://moodle.nottingham.ac.uk/pluginfile.php/6288943/mod_
tabbedcontent/tabcontent/8496/FoS%20Statement%20on%20Academic%20Integrity.pdf
A scan of handwritten notes is completely acceptable. Make sure your PDF is easily readable
and does not require magnification. Text which is not in focus or is not legible for any other
reason will be ignored. If your scan is larger than 20Mb, please see if it can easily be reduced
in size (e.g. scan in black white, use a lower dpi — but not so low that readability is
compromised).
Staff are not permitted to answer assessment or teaching queries during the assessment
period. If you spot what you think may be an error on the exam paper, note this in your
submission but answer the question as written. Where necessary, minor clarifications or
general guidance may be posted on Moodle for all students to access.
Students with approved accommodations are permitted an extension of 3 days.
The standard University of Nottingham penalty of 5% deduction per working day will
apply to any late submission.

Academic Integrity in Alternative Assessments
The alternative assessment tasks for summer 2020 are to replace exams that would have
assessed your individual performance. You will work remotely on your alternative assessment
tasks and they will all be undertaken in “open book” conditions. Work submitted for
assessment should be entirely your own work. You must not collude with others or employ the
services of others to work on your assessment. As with all assessments, you also need to avoid
plagiarism. Plagiarism, collusion and false authorship are all examples of academic misconduct.
They are defined in the University Academic Misconduct Policy at: https://www.nottingham.ac.
uk/academicservices/qualitymanual/assessmentandawards/academic-misconduct.aspx
Plagiarism: representing another person’s work or ideas as your own. You could do this by
failing to correctly acknowledge others’ ideas and work as sources of information in an
assignment or neglecting to use quotation marks. This also applies to the use of graphical
material, calculations etc. in that plagiarism is not limited to text-based sources. There is
further guidance about avoiding plagiarism on the University of Nottingham website.
False Authorship: where you are not the author of the work you submit. This may include
submitting the work of another student or submitting work that has been produced (in whole
or in part) by a third party such as through an essay mill website. As it is the authorship of an
assignment that is contested, there is no requirement to prove that the assignment has been
purchased for this to be classed as false authorship.
Collusion: cooperation in order to gain an unpermitted advantage. This may occur where you
have consciously collaborated on a piece of work, in part or whole, and passed it off as your
own individual effort or where you authorise another student to use your work, in part or
whole, and to submit it as their own. Note that working with one or more other students to
plan your assignment would be classed as collusion, even if you go on to complete your
assignment independently after this preparatory work. Allowing someone else to copy your
work and submit it as their own is also a form of collusion.
Statement of Academic Integrity
By submitting a piece of work for assessment you are agreeing to the following statements:
1. I confirm that I have read and understood the definitions of plagiarism, false authorship
and collusion.
2. I confirm that this assessment is my own work and is not copied from any other person’s
work (published or unpublished).
3. I confirm that I have not worked with others to complete this work.
4. I understand that plagiarism, false authorship, and collusion are academic offences and I
may be referred to the Academic Misconduct Committee if plagiarism, false authorship or
collusion is suspected.

SECTION A
ii) Imagine that the renewal process models the completion time of items on a production
line in a factory. Having started at time zero, a power cut occurs at time 6.25. Find
the probabilities that the product directly affected by the power cut has already
been under construction for 0.25 and 1.25 time units.
