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 allin a given year has probability 0.2, and whether or not it rains in oneyear is independent of whether or not it rains in any other year. Answerthe following questions, in each case stating clearly the probabilitymodel that you use (including the values of any parameters).What is the expected number of years with some rainfall in aperiod of 100 years?

It is given that n=100 and the probability of rains at all in a given year is 0.2.

Answered: The Atacama Desert in Chile is known as…
