Tests for tuberculosis like all other diagnostic tests are not perfect. QFT-G is one of such tests for tuberculosis. Suppose that for the population of adults that is taking the test, 5% have tuberculosis. The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time. Suppose that POS stands for the test gives a positive result and S means that the adult really has tuberculosis. Represent the "74.6%" using notation.

O P(S)
O P(S and POS)
O P(POS)
O P(POS I S)

P(POS/S)

Explanation:

Here, P(S) represents the probability that the adult really has tuberculosis,

P(S and POS) represents the probability that the adult really has tuberculosis and the test gives a positive result.

P(POS) represents the probability the test gives a positive result.

Finally, P(POS/S) represents the probability that the test correctly identifies adults with tuberculosis, which is exactly 74.6%.    

the answer is c, the development of reading and writing in young children

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
