Question 1180327: A biomedical research company produces 45% of its insulin at a plant in Kansas City and the remainder is produced at a plant in Jefferson City. Quality Conrol has shown that 1.15% of the insulin produced at the plant in Kansas City is defective while 0.55% of the insulin produced at the plant in Jefferson City is defective. What is the probability that a randomly chosen unit of insulin came from the plant in Jefferson City given that is it defective?
