What he found was very interesting. Rainy days and his mom being grouchy were entirely independent events. Some of his data are shown in the table below. Fill in the missing values from the frequency table. And let's see, we have this raining days, not raining days, and the total days that he kept data for. And then he tabulated on, say, the raining day, whether his mom was grouchy or not grouchy, and on a not raining day, whether his mom was grouchy or not grouchy. And there was a total of 35 days it rained, 330 days that it didn't rain.
