We have these four boxes here. It's not clear that we have enough information to fill it out just with this table. But we have to remember what they told us. They told us that his mom being grouchy and it raining were entirely independent events. Another way of saying that is the probability of his, let me do this in a color that you're more likely to see. Another way of saying that, so independent events, that means that the probability, my pen is acting up a little bit, probability that mom is grouchy, so let me write that. Mom, my pen is really, mom is grouchy given it is raining, it shouldn't really matter whether it's raining.
