 JavaScript has a `Math.random()` function that generates a random decimal number between `0` (inclusive) and `1` (exclusive). Thus `Math.random()` can return a `0` but never return a `1`.

 As mentioned in the previous challenge, there will be a <dfn>base case</dfn>. The base case tells the recursive function when it no longer needs to call itself. It is a simple case where the return value is already known. There will also be a <dfn>recursive call</dfn> which executes the original function with different arguments. If the function is written correctly, eventually the base case will be reached.
