Understanding “randomness”

Question

I can\'t get my head around this, which is more random?

rand()

OR:

rand() * rand()

I´m f

Answer 1

We can compare two arrays of numbers regarding the randomness by using Kolmogorov complexity If the sequence of numbers can not be compressed, then it is the most random we can reach at this length... I know that this type of measurement is more a theoretical option...
