can this code work? rgbColor = 'rgb(' + randomRBG() + ',' +randomRBG() + ',' + randomRBG() + ')';

this is the full code.

var html = '';

var rgbColor;


function randomRBG(){ 
 return   Math.floor(Math.random() * 256 );

}


for(var circle = 0;circle < 10 ; circle 
   +=1){

rgbColor = 'rgb(' + randomRBG() + ',' +randomRBG() + ',' + randomRBG() + ')';

html += '<div style="background-color:' + rgbColor + '"></div>';

There's nothing wrong with this code, but it's not complete if you want it to display something on the page.

To make the results visible, you'd need at least some CSS code to go with it, to give the div elements size and shape so they can be seen.

```function randomRBG(){ return Math.floor(Math.random() * 256 ); instead of just writing to document use this. document.getElementsByTagName("body").innerHTML = html

Multiplying random by 256 ‍does‍ give you a range from 0 to 255. The random value approaches 1 but never reaches it.
