Hmm. Interesting. So now we have a question: Does adding 1 to a random
number make it less random? It adds determinism to the number; can a
number be more deterministic while still no less random?

Ah! I know. The answer comes from common sense:

a = random()   # a is definitely a random number
a -= random()  # a is no longer random, we subtracted all the randomness from it

Of course, since number-number => number, a is still a number. And so
we can conclude that adding 1 to a random dice roll does indeed leave
all the randomness still in it. But wait! That means we can do
better!!

a = random()   # a is a random number
a *= 5   # a is clearly five times as random now!
