What if we have 100? What if we have 10,000? And so we could find the probability that we select three boys with replacement in each of these scenarios. And we could also find the probability that we select three boys without replacement. And then we could think about what proportion is our sample size of the entire population. And then we could say, does the 10% rule actually make sense? So this first column where we are picking three boys with replacement, in this case, because we are replacing, each of these trials are independent, are truly independent.
