Move mc randomly every 10 seconds

I have movie clips in the timeline and i would like them to move randomly every 10 seconds. by randomly i move, i want each movie clip to move every 10 seconds. So each movie clip will have a movement inside of it by tweening.

so will do something like

mc1.gotoAndPlay(1);

i will create a function to call mc1 and play
but i will do this every 10 seconds.

please help out.

thanks.:cons:
