It shouldn't matter whether it's raining or not. This should be 20%, this should be, she should be grouchy 20% of the time that it's raining and she should be grouchy 20% of the time that it's not raining. That would be consistent with the data saying that these were entirely independent events. So what is 20% of 35? Well, 20% is 1 5th. 1 5th of 35 is 7. And once again, all I did is I said 20% of 35 is 7.
