A point in space $(x,y,z)$ is randomly selected so that $-1\le x \le 1$,$-1\le y \le 1$,$-1\le z \le 1$. What is the probability that $x^2+y^2+z^2\le 1$?

Not sure if this is correct.

Ok there are three possibilities for x, y, and z --------> -1, 0, and 1

For $$x^2 + y^2 +z^2 \leq 1$$, at least two of the numbers have to be 0.

I don't know how to continue. Help.

But can't the $x, y,$ or $z$ be a decimal?
