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 $x^2+y^2+z^2\le 1$?
+505 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.
