I managed to create a pair of numbers with code

```
(defn dart-throwing [] 
   [(- (* 2 (rand-int 2)) 1) (- (* 2 (rand-int 2)) 1)])

(def onetrial (dart-throwing))

```

But I do not know how to create my win condition which would be `x^2 + y^2 < 1`

I tried writing

```
(defn won? [x y] 
  (< (+ (* x x) (* y y)) 1))

(won? onetrial)

```

I expected it to check the pair `[]` from dart-throwing and check if it was less than 1 giving a true or false

I would appreciate it if I had some help, thank you
