Control an MC with another MC's random actions?

[FONT=Arial]I’m not very experienced with actionscript and I need some help from you guys…

Say I have MC1 and MC2 both on the root timeline, I want to be able to click on MC1 to make MC2 go to either frame 2 or 3 at random.

What actions and instances would I apply to make this happen?

Thank you! :3[/FONT]
