Answer:

a) (X/Y) * 100

Step-by-step explanation:

In this case, the relevant data would be the number of Florida residents who had been diagnosed with asthma at any time in their life (which would be X) and the population of Florida (which would be Y).

Therefore to know the% of diagnosed or the point prevalence of asthma, it is necessary to divide X / Y, because X is the specific and Y would be the general. Therefore, the answer is a) (X/Y) * 100
