Can I plot a 3D graph of random points?

I like to incorporate some randomness in my functions.
Does Graphing Calculator 3D support random number generation?

You may use the rand() function to generate a random number between 0.0 and 1.0
If you need random number between 0 and 5.0 simply multiple the result by 5:

z=rand()*5

Here's the screen-shot of z=rand()*2
