Problem 5 - Uncertain reasoning (17 marks + 5 bonus marks)
Mr James Bond takes his car to the mechanic for regular servicing. The mechanic runs a test on
the car transmission. The test would return one of two values: 1 (Test finds Fault) or
(test finds
No Fault). The accuracy of the test is as follows: The probability of the test returning when the
car transmission is actually faulty is 0.99, and the probability of the test returning 0 when the car
transmission is NOT faulty is 0.97. After running the test on Mr James Bond's car, the test
returns 1. According to the manufacturer of Mr James Bond's car, at the age of his car, only 1 in
500 cars would have a faulty transmission.
