Interpertation
Suppose that the next bus has not arrived 15 minutes later when a second person comes along. What is the probability that the newcomer will have to wait at least 15 more minutes?

Can this be interrupted $P(T>30|T>15)\text{?}$

Yes it can be if the underlying distribution can be though of a Poisson distribution. This is due to its memorylessness property.
