Mom, my pen is really, mom is grouchy given it is raining, it shouldn't really matter whether it's raining. It should just be the same thing as the probability of mom being grouchy in general. So what does that tell us? Well, we can figure out the probability that mom is grouchy in general. She's grouchy 73 out of 365 days. So the probability that mom is grouchy in general is going to be 73 divided by 365. Or at least just based on the data we have, that's the best estimate that mom is grouchy, of the probability that mom is grouchy.
