Question: Let's assume three nodes A, B and C, within communication range of each other try to access the wireless medium using slotted Aloha. Each node

Let's assume three nodes A, B and C, within communication range of each other try to access the wireless medium using slotted Aloha. Each node transmits in a slot with probability p. If we number the slots as 1, 2, 3, ...., then answer the following questions:

(a) What is the probability that node A succeeds for the first time in slot 3?

(b) What is the probability that some node (A, B or C) succeeds in slot 3?
