Okay so Chad is the man we all know this, but this one thing he said in a QR video has me stumped and I am not sure if it is correct.
In QR42-Probability, he was going over Rain problems (ex: 90% chance of rain for each of the next 3 days, what is the chance that it rains today and tomorrow." He said that it is 9/10 x 9/10 because they are NOT independent events. However, the formula for independent events IS to multiply, and this does seem like an independent event situation since the weather of one day shouldn't affect the weather of the next. Thus, was it just a verbal mistake on his part, and he should've said that since it IS an independent event, we multiply? Thanks.
