I would like to know the desired question approach to the P5 questions because I feel am not getting the technique right and that is why I keep on failing to pass.I honestly need some guidance.

Have you checked out the Examiner’s Approach articles and the essential ‘Tackling the Exams’ article?

Hi
Is it possible for you to explain me how to calculate expected values. There is a question UNIQUE COMPONENTS. I tried a lot to calculate the probabilities and expected values but all my efforts went in vain. I will be really very thankful to you if you just tell me how to calculate them. Please explain me this part of the question. Waiting for ur reply

I don’t know what version of the answer you have, but if you take suggestion 1 of Part (b), to achieve a cost no higher than \$36.26, a cost saving of at least 12%, this is achieved when the costs fall to 36.07, 32.38, 32.81, 33.28, 33.68, 34.34. These costs are achieved with probabilities of 0.08 +0.02 + 0.03 + 0.03 + 0.01 +0.01 = 0.18.

Similarly for other proposals.
