So the mean of this distribution is P1. The variance of this distribution, we'll call that variance 1, is just these two proportions multiplied by each other. So it's P1 times 1 minus P1. And we saw this many, many videos ago when we learned about Bernoulli distributions. And we're going to see the exact same thing with the women. The mean of this Bernoulli distribution is going to be P2. And then the variance of this Bernoulli distribution is going to be these two proportions multiplied.
