8. Consider three nodes A, B and C on a 100 Mbits/sec Ethernet. Suppose these three nodes are involved in a collision which is the third collision for A's frame, fourth collision for B's frame and second collision for C's frame. After the collision is detected (we assume that all nodes detect the collision exactly at the same time), nodes calculate their backoff times according to the binary exponential backoff algorithm. i) What is the probability that the first transmission after the above collision will be a successful retransmission by C? ii) What is the probability that the first transmission after the above collision will be a collision involving all nodes? iii) What is the probability that the first transmission after the above collision will be a collision involving only nodes A and B?
