The lifetime \(T\) (in hours) of a drone battery follows an exponential distribution with parameter \(\lambda\). On average, this type of battery lasts for 500 hours.
Determine the parameter \(\lambda\) of the exponential distribution.
What is the probability that the battery lasts for at least 200 hours?
The battery has already been used for 150 hours and is still working. What is the probability that it functions for 200 more hours?
