      It is very unlikely that the exam would ask for a complicated tree. More importantly she is likely to just test your understanding with a fairly simply problem (and a fairly simple tree).
      Do realise that the whole point of the exam is to test that you understand what you are doing – not to try and make you do terribly complicated things!

    Beautiful lecture …..it seems rather a lengthy question…how often has it been examined and what is the best approach to it in terms of time mgt??

    Dear Sir, I can’t understand that why do we have an option of shutting down the office when market research has poor results ??The question indicates that if we do market research & the result is poor, then we will only be prepared to consider the cheaper refurbishment?

    shouldn’t only be cheaper refurbishment option be there if the market research has poor result , as per the question’s statement? ( And NO shutting down or expensive refurbishment should be included)

    I have a question

    31:36 – 31:57

    Do Mkt Research/Good Result/Expensive refurbishment.

    The lecture calculate
    Net expected value = Expected value – refurbishment cost
    = 12.87m – 4m = 8.87m

    Why didnt include the cost for market research:
    Net expected value = Expected value – market research cost – refurbishment = 12.87m – 4m – 0.2m = 8.67m

    I do notice its just a small difference and it would not affect the final answer but it got me puzzled abit.
