9. Nodes A, B and C are connected to the same

9. Nodes A, B and C are connected to the same Ethernet and each node is trying to retransmit a frame. The collision counters are 2, 4 and 5 for nodes A, B and C. respectively. All three nodes detected the last collision simultaneously. All other nodes are currently inactive. Node C chooses 2 as the random number according to the exponential backoff algorithm. i. What is the probability that A will be the first node initiating a retransmission attempt? ii. What is the probability that B will be the first node initiating a retransmission attempt? iii. What is the probability that the next retransmission event will be a collision involving nodes A and B only
