Re: How do i find if a number is not random ?
Assuming that you're asking about randomness defined as each number having an equal probability of being drawn, a histogram of a statistically significant sample should reveal roughly equal numbers of draws of each number, just as flipping a coin enough times should reveal that each side shows up roughly 50% of the time.
If you're asking if a random number generator is *random* or *pseudo-random*, i.e., the next number drawn is or is not dependant on previous draws, a non-random seed, etc., that's a whole other story, and a lot more complicated to determine.
