What is a group/family of functions that is random but some number(s) are more likely to come?
For example, calling each of this fake functions 10 times give:
- random2: 2,3,2,4,2,6,7,2,2,2
- random4: 4,1,2,3,4,4,2,1,4,9
As you can see,
random2 gives more number 2,
random4 gives more number 4.
Both functions have some patterns (not 100% random).
