Question 4 120 pts] Suppose users share a 3 Mbps link through circuit switching. Also suppose eaclh user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time. a) [5] How many users can be supported? b) [5] Find the probability that a given user is transmitting. c) [5] Suppose there are 120 users. Find the probability that at any given time, exactly n users are transmitting simultaneously. d) 15] Find the probability that this circuit-switching link cannot transmit data from the users (probability of failure)
