| Question 60 |
Consider a software program that is artificially seeded with 100 faults. While testing this program, 159 faults are detected, out of which 75 faults are from those artificially seeded faults. Assuming that both real and seeded faults are of same nature and have same distribution, the estimated number of undetected real faults is ______.
| 28 | |
| 175 | |
| 56 | |
| 84 |
Question 60 Explanation:
Total faults detected = 159
Real faults detected among all detected faults = 159 – 75 = 84
Since probability distribution is same, total number of real faults is (100/75)*84 = 112
Undetected real faults = 112- 84 = 28
Real faults detected among all detected faults = 159 – 75 = 84
Since probability distribution is same, total number of real faults is (100/75)*84 = 112
Undetected real faults = 112- 84 = 28
Correct Answer: A
Question 60 Explanation:
Total faults detected = 159
Real faults detected among all detected faults = 159 – 75 = 84
Since probability distribution is same, total number of real faults is (100/75)*84 = 112
Undetected real faults = 112- 84 = 28
Real faults detected among all detected faults = 159 – 75 = 84
Since probability distribution is same, total number of real faults is (100/75)*84 = 112
Undetected real faults = 112- 84 = 28
