Yeah, that's equal to 56. So there's 56 different ways to pick three things out of eight. Or if I have eight people, there's 56 ways of picking three people to sit in the car, or however you want to view it. But if I have eight flips, there's 56 ways of picking three of those flips to be heads. So let's go to our original probability problem. What is the probability that I get three out of eight heads? Well, it's the probability, it's the number of ways I can pick three out of those eight, so it equals 56, over the total number of outcomes, right?
