It is said that events are a subset of the sample space because you don't assign probabilities to individual outcomes. In a very simple sample space like that of flipping a fair coin, where the potential outcomes are only H and T, it does feel like you are assigning a probability to individual outcomes..ie. Prob of H and Prob of T.
So, if the sample space of a fair coin flip is H and T, is that a set and a subset? Is that why it makes sense?
