The WT Company turns out 10,000 widgets a day. As everyone one knows, the most important part of a widget is the idge at its center. WT buys it idges from two other companies: Ser- tane Company can supply only 2,000 idges per day, but 99% of them work properly. The remaining 8,000 idges are purchased from Kwik Company; 10% of these are defective. Suppose a randomly domly chosen widget from WT has a defective idge. What is the probability that Kwik is responsible?
