odds

[Function]
  `(``odds` prob [true] [false] [state]`)`

Returns true if a randomly generated number is less than prob, otherwise false. The default values for true and false are boolean true and false, respectively. state is a random state object and defaults to `*random-state*`

#### Examples:

Example 1. The `odds` function.

    (odds .5)
    #f
    (odds .5 60)
    60
    (odds 1)
    ⇒ #t
    (odds 0 'win)
    ⇒ #f
    (odds .2 "Yup" "Nope")
    ⇒ "Nope"

Example 2. Play octaves with increasing probability.

    (define (play-octs reps lb ub)
      ;; no octaves at start all at end
      (process with env = '(0 0 .1 0 .8 .75 1 1)
               for i below reps
               ;; probability of adding octave
               for p = (interpl (/ i reps) env)
               for k = (between lb ub k)
               for r = (odds .3 .4 .2)
               output (new midi :time (now)
                           :keynum k
                           :duration (* r 1.5))
               when (odds p)
               output (new midi :time (now)
                           :keynum (+ k 12)
                           :duration (* r 1.5))
               wait r))

    (events (play-octs 60 60 80) "test.mid")
    ⇒ "test.mid"
