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. It's the percentage of days that she's been grouchy. So that is.2. So based on the data, the best estimate of the probability of mom being grouchy is.2 or 20%.
