Suppose users share a 2Mbps link. Also suppose each user requires 300Kbps when transmitting, but each user transmits only 10% of the time.

When circuit switching is used, how many users can be supported?

For the remainder of the problem, suppose packet switching is used. Find the probability that a given user is transmitting.

Suppose there are 20 users. Find the probability that at any given time, exactly n users are transmitting simultaneously.

Find the probability that there are 7 or more users transmitting simultaneously.
