Extracted text: There are 3000 IC chips on a 12-inch silicon wafer. It is known that the probability that the chips on the wafer are defective is 3/1000 .What is the probability that atleast 3 chips will be defective on the wafer. OI NEED D A Test Engineer is testing the chips across the wafer. The engineer encounters a defective chip. What is the probability that the engineer will encounter another defective chip during the next 200 tests. Another engineer is testing a different set of chips from a different wafer and hasn't seen a defective chip for the past 50 chips. What is the probability that the engineer will test a defective chip during the next 200 chip tests?
