So the probability of getting exactly two scores in six attempts, well it's going to be any one of these probabilities times the number of ways you can get six scores, times the number of ways you can get two scores in six attempts. Well, if you have, out of six attempts, you're choosing two of them to have scores, how many ways are there? Well, as you can imagine, this is a combinatorics problem. So you could write this as, you could write this, and let me see how I could, you're gonna take six attempts, so you could write this as six choose, or we're trying to, if you're picking from six things, your six attempts, and you're picking two of them, or two of them are going to be, need to be made if you want to meet these circumstances. This is gonna tell us the number of different ways you can make two scores in six attempts. And of course, we can write this in kind of the binomial coefficient notation. We could write this as six choose two, six choose two, and we could just apply the formula for combinations.
