Reserve Problems Chapter 5 Section 5 Problem 4 Four electronic ovens that were dropped during shipment are Inspeced and classified as containing either a major, a minor, or no defect. In the past, 60% of dropped ovens had a major defect, 30% had a minor defect, and 10% had no defect. Assume that the defects on the four ovens occur independently () What is the probability that, of the four dropped ovens, two have a major defect and two have...

Consider a manufacturing line with 3 robotic machines used to create a widget. Each robotic machine either performs (P) perfectly or creates a (D) defect. Denote the outcome of the widget by creating 3-tuples of P's and D's. 1) Find the sample space S. 2) Find the event A that at least one robotic machine created a defect (D). 3) Find event B that all three robotic machines performed the same way. 4) Are the events A and B mutually...

SHORT ANSWER ( You must show all work to receive partial credit. All answers must be rigorously justified using concepts and tools from class. In the event that an answer is logically obvious to you without any mathematical justification, you must urite a justification in words.): 13. Suppose the random variables X and Y have the joint pmf given below, where the probabil- ities pi 20, p2 2 0, p3 2 0, and p 20 are such that Pi +...
X Company must replace one of its current machines with either Machine A or Machine B. The useful life of both machines is seven years. Machine A costs $52,000, and Machine B costs $65,000. Estimated annual cash flows with the two machines are as follows: Year Machine A Machine B $-6,000 $-7,000 1 -4,000 2 -8,000 3 -8,000 -3,000 4 -8,000 -3,000 5 -6,000 -3,000 6 -5,000 -2,000 -2,000 -4,000 If X Company buys Machine B instead of Machine A,...
A company manufactures four products (1,2,3,4) on two machines (X and Y). The time (in minutes) to process one unit of each product on each machine is shown below:, Product 1 in X = 10 min , in Y= 27 min Product 2 in X = 12 min , in Y =19 min Product 3 in X =13 min,in Y =33 min Product 4 in X = 8 min,in Y =23 min The profit per unit for each product (1,2,3,4)...
