I am working on a probability/statistics problem!
The problem is as follows:
Your internet connection is very poor. It constantly alternates between being functional for x minutes and being down for y minutes. If you try to check your email at a random time, how long do you have to wait, on average, to get internet connection? What is variance of this waiting time?
I don't even know how I would approach this problem because the random time of x and y minutes do not have a probability that I would need to compute the expected value (which is summation of probability * value). I guess these are expected value of continuous variables, but then again I am very stuck.
Could someone guide me through this problem? thanks!
