The probability of snow for each of the next three days is 2/3. What is the probability that it will snow at least once during those three days? Express your answer as a common fraction. Thanks for the help guys!

By using Complementary Counting, you can find the probability that no days snow, and subtract that from \(1\). The probability that no day snows is \(\frac{1}{3}*\frac{1}{3}*\frac{1}{3}=\frac{1}{27}\), so the probability of it snowing at least one day is \(1 - \frac{1}{27}= \frac{26}{27}\).
