Computer keyboard failures can be attributed to electrical defects or mechanical defects. A repair facility currently has 12 of which have electrical defects and 13 of which have mechanical defects.

If a sample of 5 keyboards is randomly selected, what is the probability that at least 4 of these will have a mechanical defect? (Round your answer to four decimal places.)

Computer keyboard failures can be attributed to electrical defects or mechanical defects. A repair facility currently has 25 failed keyboards, 8 of which have electrical defects and 17 of which have mechanical defects. (a) How many ways are there to randomly select 7 of these keyboards for a thorough inspection (without regard to order)? ways (b) In how many ways can a sample of 7 keyboards be selected so that exactly two have an electrical defect? ways (c) If a...

Use the Poisson Distribution Formula to find the indicated probability. For a certain type of fabric, the average number of defects in each square foot of fabric is 1.8. Find the probability that a randomly selected square foot of the fabric will contain at least two defects. Round your answer to four decimal places. Hint: The answer is the complement of the probability that there is at most 1 defect

A certain system can experience three different types of defects. Let Ai (i = 1,2,3) denote the event that the system has a defect of type i. Suppose that the following probabilities are true. P(A1) = 0.11 P(A2) = 0.06 P(A3) = 0.04 P(A1 ∪ A2) = 0.14 P(A1 ∪ A3) = 0.13 P(A2 ∪ A3) = 0.08 P(A1 ∩ A2 ∩ A3) = 0.01 (Round your answers to two decimal places.) (a) Given that the system has a type...

The Robotics Manufacturing Company operates an equipment repair business where emergency jobs arrive randomly at the rate of three jobs per 8-hour day. The company's repair facility is a single-server system operated by a repair technician. The service time varies, with a mean repair time of 2 hours and a standard deviation of 1.5 hours. The company's cost of the repair operation is $28 per hour. In the economic analysis of the waiting line system, Robotics uses $35 per hour...
