Question
Let the random variable X denote the time until a computer server connects to your machine (in milliseconds).
and let Y denote the time until the server authorizes you as a valid user (in milliseconds). X and Y measure the
wait from a common starting point (x <y). The joint probability density function for X and Y is:
fx, y(x, y) = ke-0.001x-0.002y for 0<x<y<∞⁰
.
.
What is the value of k?
What is the probability that X < 1000 and Y < 2000?
What is the probability that Y exceeds 2000 milliseconds?
