Pleаse nоte thаt this questiоn cоnsists of five pаrts. You may use MINITAB to find a final answer. However you MUST show all the mathematical work to get to the final answer. Just giving the answer without adequate work/explanation may result in zero for the question. Yosemite National Park operates five High Sierra camps located in a 49-mile loop. Each year they open a lottery system where people can win a "camp&hike" tour. Each year about 25% of the applicants are randomly selected to hike the High Sierra loop. Suppose you plan to enter the lottery for the next 6 years. Let X be the number of years in which you are selected to hike the loop. What is the distribution of X? Clearly state the name of the distribution and the values of the parameters of the distribution. Write down the probability mass function, for the random variable X defined above (remember to state for which values of X). What is the chance that you will win the lottery at least once in the next 6 years? What is the probability of winning the lottery at least once but no more than 3 times? Would it be unusual if you did not win the lottery even once in the next 6 years? Support your answer by show the relevant probability calculations.
