**drwls**, Sunday, February 8, 2009 at 11:18pmI do not believe you can apply statistics to weather in the manner described... Especially in Seattle, where rainy periods come in long cycles that are often incorrectly predicted. (I am from Seattle, and spend a month or two there every year). The weather you get one day is strongly correlated with that of previous days.

Reiny has given you the answer they are probably looking for, but I believe a more realistic value is more like 35%.

They picked a poor example for teaching purposes.
