hey guys,
tell me how i would approach this:
a communication system sends signals from 'a' to 'b' over 2 parallel paths. If each path has 2 repeaters with failure probablities X for the first path repeaters ,Y for the second path repeaters then what would be the probability of signal not arriving at all. The repeaters are statistically independent.
I thought it would be X*X+Y*Y.
However, i thought that if one repeater fails it won't matter if the second one fails. So they can't be statsically independent right? So how would one go about doing this?
