However, you have low chances of getting certain presents were proved as being very low according to the table posted by @Zupakode, so <strong>it is not a random event</strong>. Most of the time you will get a colored something decent at all when analyzed. The programmers set Santa Claus to give certain presents more frequently, so there is no random number generation on the code for Santa Claus NPC currently. If you are looking for the biggest prizes, you have a mathematical disadvantage set against you (just like on Slot Machines in real life, although many people think that they are random as well).</strong></p>all. Common presents are the Christmas Bundle along with something, as Bundles + Candy Canes or Snowballs + Candy Canes. <strong>I had an argument before because I looked this bias as a proof that something there isn't random, but technically it still can be considered a random ocurrance, because we can say that you have no control about what will be gifted to your data already shows.</p><p style="text-align:justify">Mathematics can provide solid evidence for it on the field of statistical analysis. One example is the Runs Test. This test can reveal a random pattern if present, through mathematical calculation. We can use an Online Tool as a resource. We can see a very easy website to operate with this statistical test right <a rel="nofollow" href="https://home.ubalt.edu/ntsbarsh/Business-stat/otherapplets/Randomness.htm">here</a></p><p style="text-align:justify">You can do it with any group of number. A <strong>P-value </strong>inferior to 0.05 will indicate that the group of numbers tested are actually following some kind of pattern or modification. Going for the analyses of the column called "<strong>Tries to get 1</strong>" resulted on a <strong>P-value</strong> of 0.00003. This is a very low number, which is accompanied by the website tool signalling as the conclusion the following statement: <strong>"Very strong evidence against randomness (trend or seasonality)"</strong>.</p><p style="text-align:justify"><img alt="" src="https://www.tibiaqa.com/?qa=blob&qa_blobid=16050568688956779465" style="height:231px; width:600px"></p><p style="text-align:justify">For more information about using the Runs Test on Excel, you can access this link and do it by yourself: https://www.youtube.com/watch?v=YWlod6Jdu-k</p><p style="text-align:justify">This friendly class can tell more in depth about details regarding the theory behind Runs Test, along with other examples: https://www.youtube.com/watch?v=9YLgBwMQoMI</p><p style="text-align:justify">You will usually receive valuable items much less often compared to Bundles.

So always "give a shot" on Santa!</p>
