Random function in Racket (more complex)

I know the basics about random function in Racket but I am trying to do something more difficult.

I am trying to develop a random function that gives randomly an element of a list I give to the function as parameter. For example:

‘(a h j l u) -> Output: h

‘(w t) -> Output: w

‘(l u t n) -> Output: t

Any help is welcome. Thank you!
