A) 0%
B) 25%
C) 50%
D) 75%

Answer 1

The probability of a positive test result on a blood sample that doesn't contain hoof and mouth disease is 0.5%.

Step-by-step explanation:

The probability that a test would be positive when applied to a blood sample that doesn't contain hoof and mouth disease depends on the false positive rate of the test. In the given information, it is mentioned that the false positive rate of the test is 0.5%. Therefore, the probability of a positive test result on a blood sample that doesn't contain the disease would be 0.5% or 0.005 (Option A).
