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 al n 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. Answe che following questions, in each case stating clearly the probability model that you use (including the values of any parameters). What is the expected value of the number of years up to and including the first year in which there is some rainfall?
