Hi I am doing the pi exercise in JuliaBox and would like to know how I could use the ternary operator ( a ? b : c ) correctly. Any suggestions?

function calculate_pi(N,r)

Acircle = 0

Asquare = 0

```
for x in 1:N
x,y = rand([-1:1]), rand([-1:1])
dist = sqrt(x^2 + y^2)
dist < r ? Acircle++ : Asquare++
end
return 4*(Acircle/Asquare)
```

end

N = 1000

r = 1

calculate_pi(N, r)

ERROR
