Flash 8 Random sound, random movieclip

Dear people, happy greetings to you all.

I would like to find some way of using a simple variable structure to do 2 things:
Pick and play a random sound from say - a selection of 5 sound files.
Do something similar with movieclips.

If you could show me where some relevant tutorials are that show how to do this or can supply some indicative code I would be most grateful.

many thanks
julie
