16 possible outcomes when you flip a coin 4 times. 16 possible outcomes. And any one of the possible outcomes would be 1 of 16. 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.
