This is one of my favorite problems. The island of Nuta is well known for its beaches and predictable warm. Sunny weather In fact Aruba's weather is so predictable that the daily newspapers don't even bother to print a forecast. Strangely enough, however, on New Year's Eve, as the islanders were counting down the last 10 sec of 2015, it began to rain What is the probability from 0 to 1, hat 72 hours were sun will be shining?
