Suppose there are three companies that produce a critical electronic navigation component (ENC) used in the aerospace industry. These companies are Alice Manufacturing, Byte International, and Cognizant Technologies. Alice makes 65% of the ENCs, Byte makes 20%, and Cognizant makes the remaining 15%. The ENCs made by Alice have a 2.5% rate of defects, the ones made by Byte have a 4.0% rate of defects, and the ones made by Cognizant have a 6% rate of defects. If an ENC is randomly selected from the general population of ENCs, and if this ENC is tested and found to be defective, the probability that it was made by Alice is 0.500 O 0.333 0.634 0.556 O none of the given choices
