That's the same. That's also exactly 4. But when you multiply them, the probability of getting any one of these particular combinations is exactly this, 0.8 to the 4th times 0.2. And so how many ways can you, if I have 5 baskets, how many ways can I pick 4 of them to be the ones that I make if I'm once again the god of probability? So this is going to be 0.8 to the 4th times 0.2 times out of 5 baskets, I'm choosing 4 that I'm going to make. So this is the number of combinations where I get 4 out of the 5. So what does 5 choose 4?
