For nonnegative X~F with mean $\displaystyle 0<\frac{1}{\mu}<\inf$

Find P(X>t+y|X>t)

I know how to do this with the exponential distribution (memoryless property), but I don't believe any information about the random variable distribution.

What is the pdf of X? Is F meant to represent this distribution: F-distribution - Wikipedia, the free encyclopedia

I think it's saying that X is distributed according to distribution F, not the particular F distribution. I think this is just a conceptual question.

Would that just be t to the infinity on top and it would all reduce to 1?
