My friend and I were having a discussion, and we both can't seem to see the other side's point of view. The question was whether a certain "operation" is random or not. This is what it is: Suppose you have an input, it doesn't matter what it is. The first "operation" is just a completely random number generator - and yes, assume for the sake of the discussion it is completely random. Even if you plug in the same number twice, you could get different numbers out. Random. Next, you add 1 to that number. I said, since the final output depended on a random input partly through the process, it was random. He replied that since you added one to it, the output was relying on a non-random operation, therefore it is not random. I'm confused about how that would make it un-random. Since the odds for every number coming out are still the same, shouldn't it be random? Or am I missing something, like the definition of random? Thanks for your help!
