A machine that manufactures automobile parts produces defective parts
13% of the time. If 10 parts produced by this machine are randomly selected, what is the probability that at least 2 of the parts are defective?
Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.

A machine that manufactures automobile pistons is estimated to produce a defective piston 3% of the time. Suppose that this estimate is correct and that a random sample of 90 pistons produced by this machine is taken. a. Estimate the number of pistons in the sample that are defective by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response. b. Quantify the uncertainty of your estimate by giving...
3 7 8 9 10 11 12 13 The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 75% of planted seeds will germinate. Suppose the manufacturer is correct. If 6 seeds planted with the fertilizer are randomly selected, what is the probability that more than 4 of them germinate? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.)
A machine produces defective parts with two different probabilities depending on its state of repair. If the machine is in good working order (G), it produces defective parts (D) with a 1% chance. If it needs maintenance, it produces defective parts with a 20% chance. The probability that the machine is in good working order is 90%. (a) What is the probability that the machine produces defective parts? Draw an appropriate tree diagram to answer this question. (b) If it...
6) If 10% of the parts produced by a machine are defective, find the probability of at least one defective part in a random sample of five. Use probability notation to solve this problem.

:Among 20 metal parts produced in a machine shop, 5 are defective. If a random sample of three of these metal parts is selected, find: 1. The probability that this sample will contain at least two defectives? 2. The probability that this sample will contain at most one defective? Note: Use hypergeometric probability formula
A new surgery is successful80% of the time. If the results of7 such surgeries are randomly sampled, what is the probability that more than 5 of them are successful? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
The probability that a part produced by a certain factory's assembly line will be defective is 0.007. Find the probabilities that in a run of 40 items, the following results are obtained. (a) Exactly 3 defective items No defective items (c) At least 1 defective item a. The probability that exactly 3 parts will be defective is (Round to four decimal places as needed.) b. The probability that no parts will be defective is (Round to four decimal places as...
Five percent (0.05) of the parts produced by a machine are defective. Twenty(20) parts are selected at random for study. A. what is the probability that more than 4 parts are defective? B. what is the probability that exactly 3 parts are defective? C. what is the expected number of defective parts in the sample? D. What is the variance and standard deviation of defective parts in the sample?
The probability thay a certain manufacturing process will produce a defective automobile tire is 0.001 the probability that an inspector will reject a defective tire is 0.98 however, the probability that an inspector will incorrectly reject a good tirr is 0.01 A)what is the probability that an inspector will reject a randomly selected tire. State answer four decimal places B)if an inspector rejects a randomly selected tire,what is the probability that the tire is actually defective? State answer three decimals...
