MATH 3023-Quiz # Name: Consider a shipment of computers. Historical data indicates that a shipment of this type has 5% of defects are with CPU only, 7% of the defects are with the RAM, and 3% of the defects are with both CUP and RAM. If a computer from this shipment is selected randomly, what is the probability that the computer has a) RAM only defects? b) neither CPU nor RAM defects?

A radio station runs a promotion at an auto show with a money box with 15 $25 tickets, 11 $5 tickets, and 12 31 tickets. The box contains an additional 20 "dummy" tickets with no value. Three tickets are randomly drawn. Find the probability that all three tickets have no value. 3. The probability that all three tickets drawn have no money value is Round to four decimal places as needed.) 4. If you are dealt 3 cards from a...
3. (3 pts) A certain large shipment comes with a guarantee that it contains no more than 15% defective items. If the proportion of defective items in the shipment is greater than 15%, the shipment may be returned. You draw a random sample of 10 items. Let X be the number of defective items in the sample. If in fact 15% of the items in the shipment are defective (so that the shipment is good, but just barely), what is...
A shipment of 94 laptops contains 5 defective laptops. A quality control specialist chooses a sample of 9 laptops from the shipment. How many possible choices of 9 laptops can be made? How many of these possible selections will not contain any defective laptops? How many of the possible selections will contain at least one defective laptop? How many of the possible selections will contain exactly one defective laptop?
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?
