Consider a software program that is artificially seeded with 100 fault...
Understanding the problem:
We are given a software program that has been artificially seeded with 100 faults. The program is then tested, and during testing, 159 faults are detected. Out of these 159 faults, 75 are from the artificially seeded faults. We are asked to estimate the number of undetected real faults.
Assumptions:
- The real and seeded faults are of the same nature and have the same distribution.
- The faults are independent of each other.
Estimating the number of undetected real faults:
To estimate the number of undetected real faults, we need to calculate the total number of real faults in the program.
Step 1: Calculate the ratio of detected seeded faults to total seeded faults.
Out of the 100 artificially seeded faults, 75 are detected. Therefore, the ratio of detected seeded faults to total seeded faults is 75/100 = 0.75.
Step 2: Calculate the total number of seeded faults.
Since the ratio of detected seeded faults to total seeded faults is 0.75, we can calculate the total number of seeded faults using the formula:
Total seeded faults = Detected seeded faults / Ratio of detected seeded faults
Total seeded faults = 75 / 0.75 = 100
Step 3: Calculate the number of real faults.
The total number of faults detected during testing is 159. Out of these, 100 faults are seeded faults. Therefore, the number of real faults can be calculated as:
Number of real faults = Total detected faults - Total seeded faults
Number of real faults = 159 - 100 = 59
Step 4: Calculate the number of undetected real faults.
The estimated number of undetected real faults is equal to the total number of real faults minus the number of detected real faults. Since all the detected faults are from the seeded faults, the number of detected real faults is 0. Therefore, the estimated number of undetected real faults is 59.
Hence, the estimated number of undetected real faults is 59.

Step 3: Calculate the number of real faults.
The total number of faults detected during testing is 159. Out of these, 100 faults are seeded faults. Therefore, the number of real faults can be calculated as:
Number of real faults = Total detected faults - Total seeded faults
Number of real faults = 159 - 100 = 59

The estimated number of undetected real faults is equal to the total number of real faults minus the number of detected real faults. Since all the detected faults are from the seeded faults, the number of detected real faults is 0. Therefore, the estimated number of undetected real faults is 59.
Hence, the estimated number of undetected real faults is 59.
