Drawing conclusions of several inferences with the same data in one study

In a sample size of 100, we identified the existence of two attributes A and B.

Our goal is to assess whether there is any association between these two attributes.

Since only the total sample size was fixed here, we conducted "Boschloo's exact test with a multinomial model".

Attribute A can be divided into two parts, "pathogenic A" and "non-pathogenic A". Now, with the same sample of 100, we test whether there is any association between attribute "B" and "pathogenic A". Since here the margin of attribute "B" is fixed, we conducted "Boschloo's exact test with a binomial model".

Again, we assessed whether there is any association between attribute "B" and "non-pathogenic A". Here we also used "Boschloo's exact test with a binomial model" as a test procedure.

My question:

In a same study, we are conducting 3 different inferences with **the same sample of 100** . Is it valid to performing several tests to draw conclusions of several inferences with the same sample?
