Explanation:
Here, in the given statement, maximum flow capacity of the ALOHA channel = 18.4% = 0.184
Then, the stations N share 56 kbps
And, the channel rate =
Then, the outputs of the wach stations is 
, the output of the bits/ sec by each stations = 
So, The output of the N stations is 10 bits/sec on the channel that having 
Finally, N =
