Please provide a detailed explanation for the question subpart c and d and e Question 3:Suppose four active nodes-nodes A, B, C and D are competing for access to a channelusing slotted ALOHA. Assume each node has an infinite number of packets to send. Each nodeattempts to transmit in each slot with probability p. The first slot is numbered slot 1, the secondslot is numbered slot 2, and so on.a. What is the probability that node A succeeds in transmitting in a slot?b. What is the probability that node A succeeds for the first time in slot 5?c. What is the probability that some node (either A, B, C or D) succeeds in slot 4?d. What is the probability that the first success occurs in slot 3?e. What is the efficiency of this four-node system?
