So if I wanted to say, so if I were to just say the probability, and I'm just going to not talk about this one head. If I just take a, just maybe this thing that has three heads right here. This exact sequence of events, this is the first flip, second flip, third flip, fourth flip. Getting exactly this, this is exactly 1 out of a possible of 16 events. Now with that out of the way, let's think about how many possibilities, how many of those 16 possibilities involve getting exactly 1 heads. Well, we could list them. You could get your heads.
