A certain manufactured item is visually inspected by two different inspectors. When a defective item comes through the line, the probability that it gets by the first inspector is 0.1. Of those that get past the first inspector, the second inspector will miss 5 out of 10. What fraction of the defective items gets by both inspectors?
