No, it is NOT random. It is a set of all possible arrangements.
For combinations, on the other hand, order does not matter, so the combinations of abc are abc OR bca OR cab, etc --- but they are all counted as the same thing. | {"url":"http://www.physicsforums.com/showthread.php?p=4214410","timestamp":"2014-04-20T00:49:29Z","content_type":null,"content_length":"33751","record_id":"<urn:uuid:c93f5b20-a376-45c4-b8f3-217e548c45c9>","cc-path":"CC-MAIN-2014-15/segments/1397609537804.4/warc/CC-MAIN-20140416005217-00322-ip-10-147-4-33.ec2.internal.w... |
