1. Suppose that a shipment of 120 electronics components contains 10 defective components. If the control engineer selects 6 of these components at random and test them

a. What is the probability that exactly 3 of those selected are defective? What is the probability that exactly 4 of those selected are not defective?

b. What is the probability that at least 3 of those selected are defective?

c. What is the probability that fewer than 4 selected are not defective?

Suppose a shipment of 180 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?
Suppose a shipment of 400 components contains 68 defective and 332 non-defective computer components. From the...
Suppose a shipment of 400 components contains 68 defective and 332 non-defective computer components. From the shipment you take a random sample of 25. When sampling with replacement (so that the p = probability of success does not change), note that a success in this case is selecting a defective part. In our sample of 25 we reject the entire shipment if X>5. What is the probability of rejecting the entire shipment?

In quality control technique, acceptance sampling is used to monitor incoming shipment of parts, raw materials, and so on. In the electronic industry, components parts are commonly shipped from suppliers in large lots. Reynolds Electronics accepts a lot from a particular supplier if the defective components in the lot do not exceed 2%. Suppose a random of 5 items from a recent shipment is tested. 1. What is the appropriate distribution that can be used here? Explain why. 2. What...

Suppose a shipment of 50 baseballs contains 3 that are defective. Baseballs from the shipment are randomly selected one at a time and checked for defects. If a baseball is found to be defective it is placed in a bin for return and reimbursement, if it is good it is put aside for use. Determine the probability that the 3th defective baseball is identified on the 10th sample.
