The Atacama Desert in Chile is known as the driest place on Earth. Suppose that in one part of the Atacama Desert, whether it rains at all in a given year has probability 0.2, and whether or not it rains in one year is independent of whether or not it rains in any other year. Answer the following questions, in each case stating clearly the probability model that you use (including the values of any parameters). Suppose that a random variable X is defined to take the value 1 when there is rainfall in a particular year and 0 when there is not. What is the mean of the random variable X?
