This wouldn't be a homework problems would it? I think it really defeats the purpose of setting such problems if you don't at least try to do them yourself. In fact, I'll be somewhat disappointed if readers of this group just dive in and answer your question. BTW, it is quite likely that your Professor or TA reads this group :-) Cheers, Paul ____________________________________________________________________ Paul Abbott Phone: +61-8-9380-2734 Department of Physics Fax: +61-8-9380-1014 The University of Western Australia Nedlands WA 6907 mailto:paul@physics.uwa.edu.au AUSTRALIA http://www.pd.uwa.edu.au/~paul God IS a weakly left-handed dice player ____________________________________________________________________
