Suppose users share a 3.3 Mbps link through circuit switching. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time. a) [5 pts] How many users can be supported? b) [5 pts] Find the probability that a given user is transmitting. c) [5 pts] Suppose there are M number of users. Find the probability that at any given time, exactly n users are transmitting simultaneously (n
