Suppose a shipment of 130 electronic components contains 3 defective components. To determine whether the shipment should be accepted, a quality-control engineer randomly selects 3 of the components and tests them. If 1 or more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?
In a 130 components 3 are defective and 127 non-defective.
Let x be the defective component,
P( X >= 1 ) = 1 - P( X = 0)
= 1 - P( none of 3 components are defective)
= 1 - 127C3 / 130C3
= 0.0682

A shipment of 30 inexpensive digital watches, including 10 that are defective, is sent to a department store. The receiving department selects 10 at random for testing and rejects the whole shipment if 1 or more in the sample are found defective. What is the probability that the shipment will be rejected? The probability the shipment will be rejected is _______ . (Simplify your answer. Type an integer or decimal rounded to two decimal places as needed.)

A shipment of 60 parts contains 9 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that at most one part is not defective? Options: 0.9439 0.0887 0.0561 0.0296
Suppose you have just received a shipment of 17 modems. Although you don't know this 2 of the modems are defective. To determine whether you will accept the shipment you randomly select 5 modes and test them. Wall modems work, you accept the shipment Otherwise the shipment is rejected What is the probly of accepting the shipmeni? Tha probability of accepting the shipment is (Round to four decimal places as needed
A shipment of 50,000 transistors arrives at a manufacturer plant. The quality control engineer at the plant obtains a random sample of 500 transistors and will reject the entire shipment if 10 or more of the resistors are defective. Suppose that 4% of the resistors in the whole shipment are defective. Describe the sampling distribution of the sample proportion of defective resistors, Justify your answer. What is the probability the engineer accepts the shipment? Do you believe the acceptance policy...

we have four boxes. box #1 contains 2000 components of which 100 are defective. Box #2 contains 500 components of which 200 are defective. boxes #3 and #4 each contain 1000 components with 100 of them being defective. a box is selected by ruling a fair four sided die and then a single item is randomly chosen from the box. a.What is the probability that the selected component is defective? b. if the selected item is defective, find the probability...
