Q3. A batch of 1000 piston rings manufactured in an engine manufacturing facility contains 40% defective. Two piston rings are randomly selected from the batch, one at a time, without replacement. If Ei denotes the event that the i th piston ring selected is defective (i=1, 2), determine the values, P(E1) and P(E2). Q4. An automobile transmission can fail due to three types of problems i.e. gear failure, bearing failure, or shaft failure, wit probabilities 0.3, 0.5 an 0.2 respectively. The probability of transmission failure given a gear failure is 0.5, given a bearing failure is 0.5 and given a shaft failure is 0.6. If a transmission fails, what is the most likely cause? Q5. In the manufacture of a fiber-reinforced laminated composite material, the following probabilities can be associated with the failure of the components made out of this material: Prob. Of failure of components Level of defect in material 0.2 High 0.05 Medium 0.01 Low In a batch of composite material manufactured, 10% of material is found to have High defects, 30% to Medium level defects and 60% to Low level of defects. For a component using this batch of material, indicate the various events associated with the failure of component as a Tree diagram. Also, determine the probability that the component fails.

If E1(E2) denotes the event of a randomly selected customer doing business with bank A(B), find the following probabilities: P(E1), P(E2), P(E1∩E2),P(Ē1Ē2) and P(Ē1UE2) Q2: The inspection of a batch of laminated composite beams produced in a company for defects yielded the following data: No. of defects Proportion of Beams with defects inside Proportion of Beams with defects on surface Total 0 0.4 0.15 0.55 1 0.1 0.05 0.15 2 0.07 0.03 0.1 3 0.06 0.02 0.08 4 0.02 0.03 0.05 5 or more 0.03 0.04 0.07 Total 0.68 0.32 1.0 Determine the probability that the beam has a defect on the surface or it has 4 or more defects. Q3. A batch of 1000 piston rings manufactured in an engine manufacturing facility contains 40% defective. Two piston rings are randomly selected from the batch, one at a time, without replacement. If Ei denotes the event that the i th piston ring selected is defective (i=1, 2), determine the values, P(E1) and P(E2). Q4. An automobile transmission can fail due to three types of problems i.e. gear failure, bearing failure, or shaft failure, wit probabilities 0.3, 0.5 an 0.2 respectively. The probability of transmission failure given a gear failure is 0.5, given a bearing failure is 0.5 and given a shaft failure is 0.6. If a transmission fails, what is the most likely cause? Q5. In the manufacture of a fiber-reinforced laminated composite material, the following probabilities can be associated with the failure of the components made out of this material: Prob. Of failure of components Level of defect in material 0.2 High 0.05 Medium 0.01 Low In a batch of composite material manufactured, 10% of material is found to have High defects, 30% to Medium level defects and 60% to Low level of defects. For a component using this batch of material, indicate the various events associated with the failure of component as a Tree diagram. Also, determine the probability that the component fails.

CIS CSC 315 01 Middleware for Enterprise Architecture – Winter 2014 Microsoft Project Objectives: Enterprise resource planning (ERP) is business management software—usually a suite of integrated applications—that a company can use to store and manage data from every stage of business, including: • Product planning, cost and development • Manufacturing • Marketing and sales • Inventory management • Shipping and payment ERP provides an integrated real-time view of core business processes, using common databases maintained by a database management system. ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across the various departments (manufacturing, purchasing, sales, accounting, etc.) that entered the data. ERP facilitates information flow between all business functions, and manages connections to outside stakeholders. Put together a PowerPoint presentation (about 15 minutes) addressing the issues below. ALL team members will participate in the presentation. The only “deliverable” is the PowerPoint presentation itself. The presentations will be the last day of class for the semester. 13-Discuss a failure or two.
