Randomness


I tried to find the definition of "random" from Wikipedia, which includes the following interesting information.
  • Randomness means different things in various fields. Commonly, it means lack of pattern or predictability in events.

  • The Oxford English Dictionary defines "random" as "Having no definite aim or purpose; not sent or guided in a particular direction; made, done, occurring, etc., without method or conscious choice; haphazard." This concept of randomness suggests a non-order or non-coherence in a sequence of symbols or steps, such that there is no intelligible pattern or combination.

  • In ancient history, the concepts of chance and randomness were intertwined with that of fate. Many ancient peoples threw dice to determine fate, and this later evolved into games of chance. Most ancient cultures used various methods of divination to attempt to circumvent randomness and fate.

Random Devices


There are many ways to generate “randomness”.
e.g., dice,

I tried to use the following two random devices:
  • Microsoft Excel: Microsoft Excel provides functions, such as RAND and RANDBETWEEN, that generate random number. I chose RANDBETWEEN because it generates an integer two specified numbers.Example, If I wish to generate an integer between 1 and 10, I can use the function as follows: = RANDBETWEEN(1,10). This may returns 4.

  • Music player:If I choose “shuffle” mode, the player randomly selects music in the music list.
