So it meets, and let me put the checks right over here, it meets this first constraint. Are the results of each trial independent? Well, whether I get a six on the first roll or the second roll or the third roll or the fourth roll or the third roll, the probabilities shouldn't be dependent on whether I did or didn't get a six on a previous roll. So we have the independence. And we also have the same probability of success on each trial. In every case, it's a 1 6th probability that I get a six. So this stays constant.
