manufacturing firm orders computer chips from three different companies:10% from Company A: 20% from Company B; and 70% from Company C. Some of the computer chips that are ordered are defective: 4% of chips from Company A are defective; 3% of chips from Company B are defective; and 0.5% of chips from Company C are defective. A worker at the manufacturing firm discovers that a randomly selected computer chip is defective. Make a tree diagram for this situation here. o...
Suppose that a computer chip company has just shipped 10 comma 000 computer chips to a computer company. Unfortunately, 60 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability. (b) The probability that the first randomly selected chip is defective is StartFraction 60 Over 10 comma 000 EndFraction equals 0.006 equals 0.6 % . Compute the probability that two randomly selected chips are defective under the assumption of independent events.
Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company. Unfortunately, 60 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability. (b) The probability that the first randomly selected chip is defective is 60/10,000 = 0.006 = 0.6%. Compute the probability that two randomly selected chips are defective under the assumption of independent events. (a) The probability is _______ (Round to eight decimal places as needed.)
and 4. A company uses three plants to produce a new computer chip. Plant A produces chips. Plant B produces 45% of the chips. The rest of the chips are produced by plant C. Each plant has its own defective rate. These are: plant A produces 3% defective chips, plant B produces 1% defective chips, plant C produces 5% defective chips. Hint: draw a tree diagram. (a) Construct a tree diagram and write the appropriate probability on each of the...
An information technology company produces 42% of its computer chips at a plant in St. Louis and the remainder of its chips at a plant in Chicago. It is known that 0.5% of the chips produced in St. Louis are defective, while 0.9% of the chips produced at the plan in Chicago are defective. What is the probability that a randomly chosen computer chip produced by this company is defective and was produced in St. Louis?
7. A lot of 100 semiconductor chips contains 10 that are defective. Three are selected, at random, without replacement, from the lot. (a) Determine the probability that the first chip selected is defective (b) Determine the probability that the second chip selected is defective. (c) Determine the probability that all three chips selected are defective. (d) Given that the second chip selected is defective, determine the (conditional) probability that all three chips selected are defective.
Question 30 1 pts A manufacturer of processing chips knows that two percent of its chips are defective in some way. Suppose an inspector randomly selects four chips for an inspection. (a) Find the probability that a randomly selected chip is NOT defective. (b) Find the probability that all four chips are NOT defective. (c) Find the probability that at least one of the selected chips is defective. (Round your answer to three decimal places).
In the electronic manufacturing assembly line, engineers observe a probability of 0.2 that a cell phone modem chip is defective. Round probabilities to the nearest three decimal places. (a) [6pts] Suppose ten chips are selected for testing, what is the probability that at most one chip is defective? Suppose 600 chips are randomly selected for testing. (b) (6pts] We can approximate the Binomial distribution with a normal distribution. Compute the mean and standard deviation of this normal distribution (c) (pts]...
A manufacturing plant produces memory chips to be used in cardiac pacemakers. The manufacturing process produces a mix of "good" chips and "bad" chips. The lifetime of good chips follows an exponential law with a rate of failure a, that is: P[chip still functioning after time t]-e-t The lifetime of bad chips also follows an exponential law, but with a much faster failure rate of 500*a. a. Suppose the fraction of bad chips in a typical batch is χ. What...
To avoid creeps from taking covert photos, iPhones bought in Japan (and seemingly also South Korea) cannot be muted when using the camera. The mandatory shutter sound was installed to reduce voyeuristic “up-skirt” photography - especially in crowded places like rush-hour trains. The chips responsible for the camera’s sound are produced at two manufacturing plants; one in Korea, and the other in Japan. The Korean factory makes 40% of the chips, while the Japanese plant produces the remaining 60%. Quality...
