And these are both Bernoulli distributions. And we know, just because this will be useful later on, we know that the means of this distribution are the same as the proportion that will vote for it. So you can see the mean of the men, or the proportion of the men that will vote. So we'll call that mean 1 is equal to P1. And the variance here, the variance of this first distribution, I should have done everything in yellow actually. I'll do everything in yellow. So the mean of this distribution is P1.
