| Question 11 |
In unit testing of a module, it is found that for a set of test data, at the maximum 90% of the code alone were tested with the probability of success 0.9. The reliability of the module is
| Greater than 0.9 | |
| Equal to 0.9 | |
| At most 0.81 | |
| At least 0.81 |
Question 11 Explanation:
Given data
Step-1: 90% of code were tested,
Testing with the probability=0.9
Step-2: We can write tested data into 0.9 because it is given in percentages.
Step-3: Reliability of the module = Tested data * probability
= 0.9 * 0.9
= 0.81(at most)
Step-1: 90% of code were tested,
Testing with the probability=0.9
Step-2: We can write tested data into 0.9 because it is given in percentages.
Step-3: Reliability of the module = Tested data * probability
= 0.9 * 0.9
= 0.81(at most)
Correct Answer: C
