Suppose nodes A, B, C, D, and E are competing to have access to a shared channel using slotted ALOHA. Each node attempts to transmit in each slot with probability p independently. The first slot is numbered slot 1, the second slot is numbered slot 2, and so on. (1) What is the probability that node B succeeds three times no later than slot 6? (2) What is the probability that there are three successful transmissions no later than slot 6? (3) What is the probability that a node succeeds three times no later than slot 6?
