1. The lifetime (in hours) of a laser diode follows an exponential distribution with mean 5000 hours.
(a) Find the probability that it lasts more than 6000 hours.
(b) Find the probability that it fails before 3000 hours.
2. Customers arrive at a service station according to a Poisson process with mean rate of 6 per hour.
(a) Find the probability that the time between arrivals is more than 15 minutes.
(b) Find the median time between arrivals.
