ReferenceError: $ is not defined error even though Jquery library is added before the function. why? and how to fix it?

Question

I'm running a simple code provided by jQuery UI that is used in a simple draggable tutorial. and I get this error:

drag.php:15 Uncaught ReferenceError: $ is not defined(anonymous function) @ drag.php:15

Why am I getting this error when I am adding the library before the function? and How do I fix it?

Screenshots of both the code and my directory where is store my libraries are attached.

Directory for Libraries

Code Used

open console and write `$` if tells undefined then try `jQuery` — Phoenix, Jun 29 '16 at 14:37
Check the paths to the JQuery includes. It might be as simple as the code not actually being present (which is normally why you see that kind of error) — steakpi, Jun 29 '16 at 14:38

Are you sure the path starts on public directory? If you're using chrome, the network tab on DevTools will show you if the .js file has been loaded.
