Say that we are in year 2025. Storms happen every year with probability p = 5%. Let RV T indicate the year of the next storm, after 2025. a) What are the mean and the std. of T? b) Consider the event A = {a storm occurs in 2026, and no storm occurs in 2027 and in 2028}. What is P[A]? c) Assume event A, defined in previous step, occurs. Let RV S indicate the year of the next storm, after 2028. What are the mean and the std of S? Say that we are in year 2025.
