Let's just say that you have, your free throw probability is P. So let's say P is, so for this situation right over here, since we generalized it fully, let's say that P is the probability of making a free throw. Actually, since I already have a P here, let me just say F is equal to the probability of making a free throw, or you could say your probability of scoring, if you call a score making a free throw. So if F is your probability of making a free throw, so if you want N scores, then this is going to be, this is going to be, well, it's going to be F to the N power, and then you're going to have, and then you're going to miss the remainder, sorry, F to the K power, because you're making exactly K scores. So F to the K power, and then the remainder, so the N minus K attempts, you're going to miss it. So it's going to be that probability of missing, and the probability of missing is going to be one minus F, so it's going to be times one minus F to the N minus K power, to the N minus K power. And just, if you like, or I encourage you, pause the video, and just make sure you understand the parallels between this example where I had a set where, I guess our F was 70%, our F was 70%, one minus F, or our F was.7, and one minus F would be.3, and we were seeing, how do we get two scores in six attempts? And here we're saying K scores in N attempts, and this is just a general way to think about it.
