Let's say I have a coin, and it's a, actually instead of unfair coin, let's do basketball. Let's say I'm shooting free throws, and I have a free throw percentage of 80%. So when I shoot a free throw 8 out of 10 times, or 80% of the time, I will make it. But that also says that 20% of the time, I will miss it. So given that, if I were to take, I don't know, 5 free throws, what is the probability that I make at least 3 of the 5 free throws? Let's think of it this way. What is the probability of any particular combination of making 3 out of the 5?
