The probability of a dry summer is equal to 0.3, the probability of a wet summer is equal to 0.2, and the probability of a summer with normal precipitation is equal to 0.5. A climatologist observed the precipitation during three consecutive summers. Find the probabilities for the following scenarios. Show steps. (a) What is the probability of observing three normal summers? (b) What is the probability of observing two wet summers? (c) What is the probability of observing at least two wet summers?
