Part – A: A firm purchases a microchip used in the manufacturing
of LED screens from four different suppliers. TechZone supplies 35
percent of the total microchips, Advance Electronics 20 percent,
PSP importers 23 percent, and TechParts inc. 27 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.
a) If a random chip is selected, what is the probability that
the chip is defective
b) A defective chip was discovered in the latest shipment. What
is the probability that it came from TechZone supplies?
c) A defective chip was discovered in the latest shipment. What
