Eighty-five percent (85%) of the material of a production company is not defective, while theremaining 15% is defective. If the material is defective, an inspector correctly determines that thematerial is defective 92% of the time; however, if the material is not defective, an inspectorincorrectly determines that the material is defective 5% of the time.a. What is the probability that the inspector determines that the material is defective?b. What is the probability that the inspector determines that the material is not defective?A material is selected at random, compute the probability that it is NOT defective, given thatc.the inspector determines that the material is NOT defective.
