If I'm forced to say, they could be cases of changing Reviewers randomly for internal control reason or, cases of 'Choosing winners' in a giveaway campaign or so on.
The following Workflow sample is a Business Process definition to play 'Word chain game' in the company. I have written about it in a blog post on the Questetra Blog, and it is totally practically useless, but a few readers want to see the 'archive', so I decided to present it as a content on this particular website again. (Of course, you can download the archive for free.)
In this example, the contestant of the Word Chain game is chosen by a random number for answering. It generates a random number just before the Splitting Gateway, and the path of the Gateway is chosen according to the random number. (Auto-Splitting)

The 'random number' we use here, is generated each time by Javascript (ECMA) function [random] in the auto-processing, "Script Task". The function [random] generates 'decimal between 0 and 1', so the script truncates the fractional from the doubled value (random()*2) to get a natural number greater than or equal to 0 less than 2.
Math.floor(Math.random() * 2); //floor: Truncation function (floor function)
If you want selection of 5, make it [Math.floor(Math.random() * 5)], if 10 [Math.floor(Math.random() * 10)]. Whenever you need random numbers in the middle of your Workflow, please use this.
* Auto-processing "Script Task": Available in version 9.7 and after of "Questetra BPM Suite", the Cloud-based Workflow.
