Answer:
The answer is 75 tests for 150 people.
Step-by-step explanation:
Firstly, with 150 people, we can divide into 15 groups; and the probability of disease is 0.04, there are 6 persons who possibly get disease.
Therefor, the maximum number of groups with an individual getting disease is 6. Then, 6 * 11 tests = 66 tests required.
15 groups - 6 groups with disease = 9 groups of negative with 9 tests.
In conclusion, there are 75 tests required.
