In proof testing of circuit boards, the probability that anyparticular diode will fail is 0.01. Suppose a circuit board contains 200 diodes. How manydiodes would you expect to fail, and what is the standarddeviation of the number that are expected to fail? What is the (approximate) probability that atleast four diodes will fail on a randomly selected board?If five boards are shipped to a particularcustomer, how likely is it that at least four of them willwork properly? (A board works...

ATV set contains five circuit boards of type A five of type B, and three of type C. The probability of falling in its first 5000 hours of use is 0.02 for a type A circuit board, 0.04 for a type B circuit board, and 0.015 for a type C circuit board. Assuming that the failures of the various circuit boards are independent of one another, compute the probability that no circuit board fails in the first 5000 hours of...

8. [10 points] 10 diodes are needed to make a circuit board. Each diode is inspected before soldering, and the probability of passing the inspection is 0.95. Only diodes that pass the inspection are soldered. Let X denote the number of diodes that are inspected in order to finish the circuit board. Determine the probability that less than 12 diodes need to be inspected. Round answer to 4 decimal places. (Hint: negative binomial distribution.)

4. In proof testing of light bulbs, the probability that any light bulb will fail is 0.05. Suppose a box contains 10 light bulbs, all which are independent of one another. A box of light bulbs can be sold only if all its light bulbs work. (a) Let X be the number of failed light bulbs. What distribution does X follow? State and name the parameters (b) How many light bulbs would you expect to fail, and what is the...

When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 5%. Let X = the number of defective boards in a random sample of size n = 25, so X~ Bin(25, 0.05). (Round your probabilities to three decimal places.) (a) Determine P(X ≤ 2). (b) Determine P(X ≥ 5). (c) Determine P(1≤ X≤ 4). (d) What is the probability that none of the 25 boards is defective? (e) Calculate the expected value and standard deviation of X. (Round...

Ask Yout Teache of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the numerous types of solder defects (e.g. pad non- Human visual in wetting, knee visibility, voids) and even the degree to which a joint possesses one or more of these defects. Consequently, even highly trained inspectors can disagree on the disposition of a particular joint. In one batch of 10,000 jolints, inspector A found 742 that were judged defective, inspector...

In a certain store, there is a .02 probability that the scanned price in the bar code scanner will not match the advertised price. The cashier scans 844 items. (a-1) What is the expected number of mismatches? (Round your answer to the nearest whole number.) Expected number (a-2) What is the standard deviation? (Use your rounded number for the expected number of mismatches for the calculation of standard deviation. Round your final answer to 4 decimal places.)...

The probability that a customer's order is not shipped on time is 0.06. A particular customer places three orders, and the orders are placed far enough apart in time that they can be considered to be independent events. Round your answers to four decimal places (e.g. 98.7654) (a) What is the probability that all are shipped on time? (b) What is the probability that exactly one is not shipped on time? (c) What is the probability that two or more...
