Because it rains on the quarter of the days, <em>the odds are ¼</em> that it is going to rain at some point on a given day. <u>For example</u>, we have 30 days in a month, it rains during 7.5 days. Meanwhile, we do not know on which days it is going to rain and at what time of the given day. Thus, on every day at every point of the each day there ¼ (25%) chance of rain during this time of the year.
