It's not a stupid question. But I believe the answer depends on the details of the test. For some tests, the probabilities on successive tests will be correlated, and for others, they won't. My impression is that part of what people learn when they become medical specialists is when it makes sense to repeat the same test, and when it makes sense to look for a different test with uncorrelated errors.
