(I) S can launch a birthday attack to replace m with a fraudulent message. (II) A third party attacker can launch a birthday attack to replace m with a fraudulent message. (III) R can launch a birthday attack to replace m with a fraudulent message. Which of the following are possible security violations?
Consider a network connecting two systems located 8000 kilometers apart. The bandwidth of the network is 500 106 bits per second. The propagation speed of the media is 4 106 meters per second. It is needed to design a Go Back N sliding window protocol for this network. The average packet size is 107 bits. The network is to be used to its full capacity.

The probability of sending a frame in the first slot without any collision by any of these four stations is ________.
