So not yellow. From previous videos, we know some interesting things about this Bernoulli random variable. We know its mean. We know the mean of our Bernoulli random variable is going to be the proportion of yellow balls in this population. So it's going to be equal to P, which in this particular case we know is 0.6. And we know what the standard deviation of this Bernoulli random variable is. It is going to be P times one minus P. Actually, that's the variance.
