I dont exactly undrestand how to start thinking about it, any pointers, would be great.

A chemist runs a process until it fails. Let X be the number of times the process must be run before a failure occurs. Past data collection shows that X follows a Poisson distribution and that the expected of times the process must be run before failure is 14. For the next time the process is tested, what is the probability the failure more runs of the process? For the next time the process is tested, what is the probability that the number of times the chemist must run the process before a failure occurs is within one standard deviation of the expected value for X?
