Question:
Elevators arrive randomly at the ground floor of an office building. Because of a large crowd, a person will wait for time W in order to board the third arriving elevator. Let X1 denote the time (in seconds) until the first elevator arrives and let Xi denote the time between the arrival of elevator i - 1 and i. Suppose X1, X2, X3 are independent uniform (0, 30) random variables. Find upper bounds to the probability W exceeds 75 seconds using
(a) The Markov inequality,
