Question

In a multiuser wireless network the data frames are being transmitted when the probability of collision during the transmission is 0.75. The transmitters try to send the collision-free frames using up to 6 independent trials (transmission) as needed. The transmitters indefinitely discard the data frames after 6 failures. Calculate the probability that a data frame can be successfully transmitted (not be discarded). Let ? denote the random number of trails until the frame is transmitted without collision, find ?(? ≤ 5) =?
