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. And if our trials are independent, then x would be truly a binomial variable. Here, we aren't independent because we are not replacing, so not independent. And so officially, in this column right over here when we're not replacing, x would not be considered a binomial random variable. But let's see if there's a threshold where if our sample size is a small enough percentage of our entire population where we would feel not so bad about assuming x is close to being binomial. So in all of the cases where you have independent trials and 50% of the population is boys, 50% is girls, well, you're going to amount to 1 1⁄2 times 1 1⁄2 times 1 1⁄2. So in all of those situations, you have a 12.5% chance that x is going to be equal to three.
