racket - figure with random digits

I am trying to write recursive function that will generate figure with n random digits. To generate a numbers I want to use (random 10). I want function to decrease n until it reachs 0.

(define (generate-number n)
  (if (= n 0) 0
       (generate-number (- n 1))))

Can someone please help me where to place (random 10) and make this work.
