Messages arrive to a computer server according to a Poisson distribution with a mean rate of 5 per hour. a- Determine the probability that at least three messages arrive during 2 hours. b- Determine the probability that exactly two messages arrive in one hour. c- Determine the length of an interval of time such that the probability that no message arrive during this interval is 0.9.
