Roll a Random Number. Say "Wolfram, random integer." Wolfram returns a random value between 0 and 1000. "Wolfram, random number" provides a 0 to 1 floating point value. Look up nature facts.

So, how about I just give a quick review of some different ways to do this. For all these methods, I will put in a calculator to determine the density of something given its mass and volume.

Type how you're related into Wolfram Alpha's computation engine, and it returns the relationship—first cousin once removed, in that last example.
