I'm bit confused, isn't counting desirable outcomes vs possible outcomes standard way of teaching probability? How is nCr/nPr stuff explained if not in the context of counting outcomes? I'm also confused where does set theory come in here?

To begin, Sample Space of Events is a Set. Simple cases like probability of A or A's complement etc., all rely on basic set theory. The rabbit hole is sample spaces that are really really large. What happens to probability distribution of desired events in those cases?
