False, if A B , C then the hypothesis is trivial, but the conclusion is not.

"The population, for a disease D, has a true rate of T%"
"Some Test ST, has false positive rate of FP% and a false negative rate of FN%."
"T, FP, and FN are elements of the set of real numbers."
Was the number T determined by some 100% accurate and possibly expensive test?

For what composite numbers x will a x 1 1 ( mod x ) for a [ 2 , n ]?
Can we generate xs that give false positives to the Rabin-Miller test for the first, say 10, consecutive integers a > 1?

Let X be a locally comapct and Hausdorff space. We say a positive Radon Measure on X is faithful if
0 f       ,       f d μ = 0 f ( x ) = 0     x X
True or false: If there is a faithful positive Radon measure on X then X has a countable dense subset ?

While it makes some sense, it's not clear to me why those are different. If a test, say medical test, is correct 90% of time then chances of it being wrong is 10%.
There are 4 events
1. Test is +, patient has a disease
2. Test is -, patient doesn't have a disease
3. Test is +, patient doesn't have a disease
4. Test is -, patient has a disease

A pregnancy test kit is 98.5% accurate for true positive result, i.e. the result is positive when the tester is actually pregnant. If she is not pregnant, however, it may yield a 0.8% false positive. Suppose a woman using this pregnancy kit is 60% at risk of being pregnant.
Not sure about her first test which turned out to be negative, the woman decides to take the test again. This second test, however, turns out to be positive. Assuming the two test are independent, find the probability that she is actually pregnant.
Now she is so confused whether or not she is pregnant. So she take the tests n more times and the results for these n more tests are all positive. Find the minimum value for n so that she can be at least 99.99% sure of pregnancy, assuming all test are independent.

The occurrence of false positives [in some experiment] is 40%
What does this mean? Does it mean that 40% of positives are false? Or 40% of all tested patients are specifically both false and positive? Or say 40% of those that are false are positive?
