Q86 A subassembly is made up of three components A, B, and C. A large batch of these units are supplied to the production site and the proportion of defective units in these is 5% of the component A, 10% of the component B, and 4% of the component C. [5 Marks]

(a) What proportion of the finished subassemblies will contain no defective components?

(b) What proportion of the finished subassemblies will contain exactly one defective component?

(c) What proportion of the finished subassemblies will contain at least one defective component?

(d) What proportion of the finished subassemblies will contain more than one defective component?

(e) What proportion of the finish?

Answer #1

Probability of defectives= 0.05+0.1+0.04= 0.19

Probability of non-defectives= 1-0.19= 0.81

By using binomial probability distribution formula the following would be calculated as followed:

a)Contains no defective

b) exactly one defective

c) atleast one defective

d) more than 1 defectives

Q68 A branch of BNP-Paribas has an attractive credit programme. Customers meeting certain requirements can obtain a credit card called “BNP Wunder”. Local merchants in surrounding communities accept this card. The advantage is that with this card, goods can be purchased at a 2% discount and further, there is no annual cost for the card. Past data indicates that 35% of all card applicants are rejected because of unsatisfactory credit. Assuming that credit acceptance, or rejection, is a Bernoulli process,...

We constantly seem to be pricing ourselves out of some markets and not charging enough in others. Our pricing policy is pretty simple: we mark up our full manufacturing cost by 50%. That means a computer that costs us $2,000 to manufacture will sell for $3,000. Until now I thought this was a workable approach, but now I’m not so sure. Steve Works, CEO, Cortland Manufacturing, Inc. (CMI) Steve’s Controller, Sally Nomer, had just told him that she believed the...
