jQuery: this random selector is rather predictable
<p>In this fiddle <a href="http://jsfiddle.net/SySRb/40/" rel="nofollow">http://jsfiddle.net/SySRb/40/</a>, I created an array with two elements, #f-ONE and #ONE. There is a function that, when the "start" box is clicked, selects one of the two elements randomly, and, depending on which is chosen, displays either a yellow or reddish box. </p>

<p>However, in actual fact, it is always the yellow box that is selected, so something is not working.</p>

<p>However, the exact same code that selects things randomly works in other contexts (see <a href="http://jsfiddle.net/urfXq/96/" rel="nofollow">http://jsfiddle.net/urfXq/96/</a> ), so I don't know what the problem is... </p>
