Factories I and II produce phones for brand ABC. I produces 60% of all ABC phones, II produces 40%. 10% of phones produced by I are defective, and 20% of those produced by II are defective. You know that the store where you buy your phones is supplied by one of the factories, but you don't know which one. You buy two phones, and both are defective. What is the probability that the store is supplied by factory II? Make...

4. Costs in the short run versus in the long run Ike's Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company's short-run average total cost (SRATC) each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total...

Question 1 [12 + 4 =16 marks] A. Let A and B be two events such that P( A) 0.6 , P(B) 0.4 and P( A B) 0.10. Calculate P( A B). Calculate P( A | B). iii. Are events A and B independent? Justify your answer. iv. Are events A and B mutually exclusive events? Justify your answer. (2 + 2 + 3 + 3 = 10 marks) B. A box contains 20 DVDs,...

5. Assume the stock return for the next month is a random variable that follows a Normal distribution with the mean 1.5% and the standard deviation 5%, which is the true probability. The interest rate is 0.2% for the next month. Suppose you are the owner of a big investment bank, and one of your VIP clients wants to buy a customized derivative from you. The payoff of such derivative is...

This question has three parts. Part 1. The data and scenario from this question follows into the next two questions. A plumbing company sells plumbing supplies for commercial and residential applications. The company currently has only one supplier for a particular type of faucet. Based on historical data that the company has maintained, the company has assessed the first accompanying probability distribution for the proportion of defective faucets that it receives from this supplier. This supplier charges the company $33.00...

Description When you want to knit an object by hand you purchase a pattern and yan. The pattern tells you how to perform the knitting and how much yarn is needed to knit the object in the yarn that the designer used. Yarn comes in balls. Each ball of yarn has a gven number of yards, but this number varies from one type of yarn to another. It can be impossible to find the same yarn that the pattern calls...
