In a swapping system with variable partitions,  segments have probability
      
                      -s/10
      distribution ( e     / 10) where s is the segment size in kilobytes. Holes
                                        
                                         -h/5
      have  probability distribution  ( e    / 5) where h is the hole size in 
      
      kilobytes.  What  is the average fraction of wasted memory in external
     
      fragmentation?

 

reference:- https://cseweb.ucsd.edu/classes/fa99/cse120/q2soln.html

 

i’m stuck at how average segment segment size and average hole size is calculated?

please comment if you have got any insight.
