Now another condition for being a binomial variable is that you have a fixed number of trials. Fixed number of trials. So in this case, we're saying that we have 10 trials, 10 flips of our coin. And then the last condition is the probability of success, and in this context, success is a heads, on each trial, each trial is constant. And we've already talked about it. On each trial on each flip, the probability of heads is going to stay at 0.6. If for some reason that were to change from trial to trial, maybe if you were to swap the coin and each coin had a different probability, then this would no longer be a binomial variable.
