Let's keep going. So the probability that X is equal to two, well that's what our first video was, essentially. So this is going to be six choose two times 0.7 squared times 0.3 to the fourth power. And we saw that this is approximately going to be 0.06, or we could say 6%. And obviously you could type these things in a calculator and get a much more precise answer, but just for the sake of just getting a sense of what these probabilities look like, that's why I'm giving these rough estimates. Kind of, I guess you could say to the closest, maybe tenth of a percent. And actually if you round to the closest tenth of a percent, you actually get to 6.0%, and this is 1.0%, because this we actually went to a tenth of a percent here.
