So pretty much any particular, the probability of getting any particular combination of three baskets and two misses is going to be 0.8 to the third times 0.2 squared. Now, what's the total probability of getting 3 out of 5? Well, it's going to be the sum of all of these combinations. You know, I could list them all, but we, hopefully now, are proficient enough in combinatorics and combinations to figure out how many different ways, if we have 5 baskets and we're picking, or we have 5 shots, and we're picking 3 of them to be the ones that are basket shots. What do I mean? So let's say my 5 shots, so I have shot 1, 2, 3, 4, 5. And I'm going to, out of these 5, I'm going to choose 3.
