Suppose that we have a more complicated channelmodel than on Homework #1. In particular, we have a channel that is either Bad ("B") with probability0.2 or Good ("G") with probability 0.8. If the channel is Bad, the random signal gainXobeys:(-2t1-e,t0P(Xt|B) =0,t <0.If the channel is Good, the random signal gainXobeys:(-0.5t1-e,t0P(Xt|G) =0,t <0.(a) FindP(X >1.5).(b) Suppose that you observeP(X1.5). What is the probability that you are experiencing a Badchannel
