AP2.9 Suppose that you have torn a tendon and are fac- ing surgery to repair it. The orthopedic surgeon explains the risks to you. Infection occurs in 3% of such operations, the repair fails in 14%, and both infection and failure occur together 1% of the time. What is the probability that the operation is successful for someone who has an operation that is free from infection? (c) 0.8600 (a) 0.8342 (b) 0.8400 (d) 0.8660 (e) 0.9900 T5.4 Computer voice recognition software is getting better. Some companies claim that their software correctly recognizes 98% of all words spoken by a trained user. To simulate recognizing a single word The when the probability of being correct is 0.98, let two digits simulate one word; 00 to 97 mean "correct." program recognizes words (or not) indepen- dently. To simulate the program's performance on 10 words, use these random digits: 60970 70024 17868 29843 61790 90656 87964 The number of words recognized correctly out of the 10 is (a) 10 (b) 9 (c) 8 (d) 7 (e) 6
