find_all is not a method of the Array class, but an instance method of the 
Enumerable module, which is mixed-in in class Array. If you look at the online 
documentation for Array, you'll see that there's a section called "Included 
Modules", which contains Enumerable. Clicking on it, you'll be directed to the 
documentation for the Enumerable module, knowing that all its instance methods 
are also instance methods of Array.
