A firm purchases a microchip used in the manufacturing of LED screens from four different suppliers. TechZone supplies 32 percent of the total microchips, Advance Electronics 20 percent, PSP importers 23 percent, and TechParts inc. 25 percent. TechZone tends to have the best quality, as only 1 percent of its microchips arrive defective. Advance Electronics chips are 3 percent defective, PSP importers chips are 6 percent defective, and Parts Inc. are 5.5 percent defective. If a random chip is selected, what is the probability that the chip is defective A defective chip was discovered in the latest shipment. What is the probability that it came from TechZone supplies? A defective chip was discovered in the latest shipment. What is the probability that it came from TechParts Inc.?
