Suppose a computer chip manufacturer rejects 2% of the chips produced because they fail presale testing. What's the probability you find a bad one within the first 10 you examine?

Suppose a computer chip manufacturer rejects $2\%$ of the chips produced because they fail presale testing. In a random sample of 400 chips, what is the mean number of chips that are expected to fail?

Suppose a computer chip manufacturer rejects $2\%$ of the chips produced because they fail presale testing. In a random sample of 400 chips, what is the mean number of chips that are expected to fail? What is the standard deviation of that same sample?

A manufacturer of computer chips finds that 1% of the chips produced are defective. What is the probability that out of 8 chips, at least 2 are defective?

Assume a computer chip manufacturer rejects $2\%$ of the chips produced because they fail presale testing. Considering the bad chips are independent, find the likelihood of the following:

a) The fifth chip they test is the first bad one they find.

Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company. Unfortunately, 50 of the chips are defective.

Compute the probability that two randomly selected chips are defective using conditional probability.

Suppose a computer chip manufacturer rejects 2% of the chips produced because they fail presale testing.

a) What's the probability that the fifth chip you test is the first bad one you find?

b) What's the probability you find a bad one within the first 10 you examine?

Suppose a computer chip manufacturer rejects $2\%$ of the chips produced because they fail presale testing. How many do you expect to test before finding a bad one?

Last year, the Computer Company sold $200,000,000 worth of its computer chips out of a total market of$1,428,000,000. What market share did it have in computer chips?

Only 4% of people have Type AB blood. On average, how many donors must be checked to find someone with Type AB blood?

A basketball player has made 80% of his foul shots during the season. Assuming the shots are independent, find the probability that in tonight's game he makes his first basket on his fourth shot.

A basketball player has made 80% of his foul shots during the season. Assuming the shots are independent, find the probability that in tonight's game he misses for the first time on his fifth attempt.

A Department of Transportation report about air travel found that, nationwide, 76% of all flights are on time. Suppose you are at the airport and your flight is one of 50 scheduled to take off in the next two hours. Can you consider these departures to be Bernoulli trials? Explain.

A grocery supplier believes that in a dozen eggs, the mean number of broken ones is 0.6 with a standard deviation of 0.5 eggs. You buy 3 dozen eggs without checking them. a) How many broken eggs do you expect to get? b) What 's the standard deviation? c) What assumptions did you have to make about the eggs in order to answer this question? Do you think that assumption is warranted? Explain.
