So let's just think about this a little bit. Probability of A given that B has happened. Given that B has happened. So essentially, we are restricting our equally likely possibilities now to the situation where B has happened. Given B means we're assuming that B has happened. So now we're restricting our sample space of possible outcomes where B has happened to this right over here. So now there are one, two, three, four, five, six equally likely outcomes.
