Question: i . There are only three active stations in a slotted Aloha network: A , B , and C . Each station generates a frame

i. There are only three active stations in a slotted Aloha network: A, B, and C. Each station generates a frame in a time slot with the corresponding probabilities pA =0.2, pB =0.3, and pC =0.4 respectively.
Solve for
a. The probability that any station can send a frame in the first slot?
b. The probability that station A can successfully send a frame for the first time in the second slot?
c. The probability that station C can successfully send a frame for the first time in the
third slot?
