-    Generate a list of random indices based on a specified percentage of the total size.
+    Generate a list of random indices based on the specified proportion of a given size.
     The indices are selected from the range [start, start + size).
 
     Args:
         start (int): Starting index (inclusive). It's the first index that could possibly be selected.
         size (int): Size of the collection to select from. This is the total number of indices available.

-        percentage (int): Percentage of indices to select from the specified range [0 to 100].
-            For example, 30 would mean 30% of the total size, and 50 would mean half of the total size.
