If your circuit provides a function random, you want to either

(define (1-10-rand)
    (+ 1 (random 10)))

or

(define (1-10-rand)
    (floor (* 10 (random))))

depending on whether you have (random n) --> integer in [0, n-1])or(random) -> float in [0,1]

Please note that this is not up to standard. For ultimate mobility, write your own RNG.
