I need a response and question for this discussion:

To say the files were randomly selected means, that they were not predetermined to be selected. So for the researcher to randomly select files, he or she would have to choose them from different files but from the same type of research.The process would look like according to (Heiman G. 2015), “random chance—the “luck of the draw” of who we happen to select for a sample. Thus, maybe, simply because of who happened to enroll in your statistics class, it contains some very unusual, atypical students who are not at all like those in the population.”
a) The probability of a student file falling in each of the following categories such as mental health probability would be 25/50=0.5
b) The probability of a student file falling in each of the following categories such as learning/school issues or relationship issues probability would be (15+5)/50
c) The probability of a student file falling in each of the following categories such as any category except other probability would be (50-5)/50=45/50=0.9
Probabilities and results would be different if we used convenience sampling. This is because convenience sampling is usually taken from a group that you have easy access to, as in if you are trying to say something about children then your convenient study will not be on men.
