Suppose that bugs are present in 1% of all computer programs. A computer de-bugging program detects an actual bug with probability 0.99, but falsely detects a nonexistent bug with probability .02. Give numerical answers to each of the following questions: (i) If the de-bugging program claims to have found a bug in program A, what is the probability that the bug is actually present? (ii) Suppose that Program A is tested twice, the two tests conducted independently. If the de-bugging...
