A factory tests all its products. The proportion of defective items is 0.01. The probability that the test will catch a defective product is 0.95. The test will also reject nondefective products with probability 0.01. Given that a product passes the test, what is the probability that it is defective? (b) Given that the product does not pass the test, what is the probability that the product is defective?
